A student asked a straight teacher why he wore a rainbow shirt. His answer was perfect.

Every generation and decade has its slang. These days, young people often use slang terms and phrases, such as “slay,” “no cap,” and “bet,” which can be hard to understand if you’re older than 25. But, of course, that’s the point. If you think these kids are unintelligible, what do you think would happen if you sent them back in time to 1992 and they had to figure out what Pauly Shore was saying in Encino Man?

Could a Gen Zer figure out what he meant when he said, “If you're edged 'cause I'm weazin' all your grindage, just chill"? Or would they know what Shore meant when he said, “The truth is, bro, life's about greasing the 'do back, buddy, and wheezin' on the buff-fest, man"? Probably not.

To help remind everyone that people in the ‘90s had their own bizarre slang, too, a Redditor named @NoahtheAttacker asked folks on the AskReddit subforum, “What’s the most ‘90s slang/phrase?” and reading the responses is like taking a time machine back to the era of Bill Clinton, neon-colored clothing, and In Living Color.

Here are 13 of the best responses, with our best attempt at explaining them to the older and younger generations.

1. "Not!"

For the uninitiated, this phrase was used to negate the sentence that came before. For example, President George Bush, who famously disliked broccoli, would say, "I love broccoli," then pause for two seconds, and say, "Not!" You must say "not" in a very obnoxious way. Or, in the song "Wayne's World Theme" from the Wayne's World soundtrack, Mike Myers and Dana Carvey sing, "The right to party is a battle we have fought / But we'll surrender and go Amish... Not!"

2. "Talk to the hand"

The complete line of this phrase is, "Talk to the hand because the face don't give a damn" and it was used in the '90s to aggressively turn down a request. For instance, if someone you didn't like asked you for a date, you would put your palm up in a stop position and say, "Talk to the hand," which means stop there; I'm not listening.

3. "All that and a bag of chips"

This phrase was used when referring to someone who excels at a specific activity, such as playing football or rapping. It's also used to refer to someone very attractive, as in the title of the 1999 film, She's All That, starring Rachel Leigh Cook. The "bag of chips" was added later to take things up a notch and make them even better, much like the addition of some Doritos on the side of your Subway sandwich.

4. "Mad"

Now, if you're a Gen Zer, you may think that adding the term "mad" to something means it's angry. On the contrary, to say someone is "mad hungry" means they are very hungry. If you are mad rich, then you are wealthier than Uncle Phil on The Fresh Prince of Bel-Air. If you have "mad skills," that means that you excel at a specific task.

5. "As if"

"As if" is a shorter way of saying, "As if I would ever..." Here's an example: "You want me to choose those '80s Jordache jeans over these sweet Z Cavaricci pants? As if." Or, "You think that I would choose to date Tiffani Amber Thiessen over Pamela Anderson? As if." To take things up a notch, you could add a "whatever" after the "as if" to really drive the point home.

6. "Word"

"Word" is a simple way to confirm something someone else had said. "You like that new bar-b-que burger at Carl's Jr.?" you'd ask your friend, and they would respond with "Word," meaning "yes." To make it even more emphatic, say, "Word up!" or to be super affirmative, "Word to your mother!"

7. "Homey don’t play dat"

"Homey don't play dat" was the catchphrase of Herman Simpson, aka Homey D. Clown, a bitter and hostile convict with a never-ending community service sentence, on TV's sketch show, In Living Color. Whenever a child on the show would ask Homey to do something clownish, he would respond, "Homey Don't play dat," and then whop the kid over the head with a sock containing a tennis ball inside. Colloquially, it was used to turn down people's requests. For example, if someone asked if you could work late on your shift at Musicland, you could respond, "Homey don't play dat."

8. "Whatever"

"Whatever" is one of the most popular phrases of the '90s, and it perfectly encapsulates the Gen X mindset. It means, "I'm not impressed," "screw off," and "I don't care." It's a great way to blow someone off without having to provide a reason why.

9. "Tight!"

This is a great term that remains relevant today, referring to something truly exceptional. If you perfectly execute or agree with what someone is saying, you say "tight." For example, if someone asked you, "Hey! You want to get a Pizazz pizza at Taco Bell?" You'd respond with, "Tight." Or another use would be, "Did you see Arrested Development on Arsenio Hall last night? They were so tight."

10. Cowabunga, dude

"Cowabunga" is a 1960s surfer slang term that gained mainstream popularity in the 1990s after being popularized by Bart Simpson and the Teenage Mutant Ninja Turtles. It basically means, "that's great" or "go for it!"

11. "Extreme"

In the 1990s, extreme sports were huge, whether that meant bungee jumping or wing suiting off the top of a mountain. Therefore, anything that was particularly intense, whether it was soda with a fierce flavor or nachos that were loaded higher than usual, was called extreme. Vanilla Ice's debut album, featuring the song "Ice Ice Baby," was called To the Extreme.

12. Da bomb

If something is really incredible, it's "da bomb." For example, you'd say, "Ahhh man, the new chili cheese fries at 7-11 are da bomb." Additionally, to make things more fun, you could say they were "the bomb diggity."

13. "Psych!" or "Sike!"

This is similar to the "not!" joke referenced above. You call "psych" on something when you psyche someone out or fool them. For example, if your friend really liked a girl named Heather, you could say, "Heather was totally scamming on you at lunch today." Surprised you'd say, "really?" But then your buddy would pull the rug out from underneath you with a "Psych!" and everyone would laugh at you.
