"Look, this face seats five."
Billy, to some chick who said she was with friends. Schumacher probably thought that was the coolest line of '85
"Wife? You're not married to me, you're married to your friends and the bar!"
Felicia to Billy
"Well,
that's
outta hand. Jeez."
Wendy, after Billy nearly fell off the roof

Yes, "it's ok, the wet look is in," takes the cake. Just imagine how filthy that bar toilet must have been! Billy didn't even attempt to rinse his hair off, dry it with towels, or leave to go take a shower. He didn't even wash his hands after touching it! GAG!!!!!!
I also found it particularly offensive when Jules was making fun of the food at the homeless shelter, although I forget the exact line. Especially after the cook told Wendy he didn't have enough to begin with and then Jules didn't even eat it so it went to waste.

I do have to give some slack for the "tired at 22" line as I can say I personally felt that way during the same year of my life. I was newly married and struggling horribly to be an "adult". Even my daughter echoed the same thing recently at 22 as she thought her post-college job was killing her (she since leveled off after getting a promotion).
"That's ok, the wet look is in." Billy says this after getting his head dunked in the toilet of a college bar. I would have found the nearest fire extinguisher and bashed Alex's face in.

Oh man this thread has me in tears!
I love this movie, but yes it has some of the most ridiculous dialogue of all time. Being older now I really can't deal with Jewel's "I never thought I'd be so tired at 22" line. She needed to get a grip.
Here's my list of laughable lines:
"Let's rock"
"No Springsteen is leaving this house!"
"You're not gonna believe how outta hand it's gonna be."
"A booga booga booga booga ah ah ah!"
"You break my heart. Then again you break everyone's heart."
"I'm taking Thriller and Mahler's ninth.
Kevin is so fond of Mahler."
"We're all going through this. It's our time at the edge."
That being said here are some lines I think are great:
"Hey I never lied to you once you cocky sh!thead!"
Wendy's peanut butter & jelly story.
"Love sucks"
"So does your attitude."

Aw, I actually like that line.
I want the doctor to take your picture so I can look at you from inside as well.

(alec) You beep Kevin! (leslie) You beep many! ughsuch BAD dialogue.

This film, as lovable as it is, is indeed fraught with more than its share of cringeworthy lines. In addition to most of the stinkers already listed, I can't stand the following exchange:
Kevin: "Marriage is extinct."
Alec: "
Dinosaurs
are extinct.
Marriage
is still around."

"I always KNEW he was a Republican!" Exactly how?
Kevin sharing his bottle with the prostitute. No offence, but god knows where that mouth has been. And it was 1985!
That whole scene where Billy gets back with his wife at the Halloween party. She shows up with another guy while he plays sweaty rock with a band called The New Breed. Then he makes out with Jules while the other woman he wants to bang looks on. A fight break out and THEN they decide to reconcile.
Still, though, one of my favorite "bad" movies. Still fun to watch after 30 years.

I thought every line between Leslie and Alec about who takes which albums was cringe-worthy. Just bad writing all around in that scene.

I saw this in a movie theater in NYC during its premiere week and the audience went nuts when Estevez said
Later dude
.. then drove off down the snowy mountain. I guess that was Estevez' signature line. Back then, it seemed too So Cal for an East Coast Georgetown grad to utter. Then again we never got much back story on Kirbo, who could've been from California originally.

What donelp said.

Sorry, thank you for playing anyway. This was the BEST line of the movie.

I'm Obsessed, thank you very much!

You know what love is? Love is an illusion created by lawyer types like yourself to perpetuate another illusion called marriage to create the reality of divorce and then the illusionary need for divorce lawyers.
It's not the fat chick.
Haven't you heard of the sexual revolution?
Who won, huh? Nobody. Used to be sex was the only free thing, No longer. Alimony palimony it's all financial. Love is an illusion.
Never trust a woman who says she isn't angry.
College is like this four year delusion so you don't have to deal with reality.

"Look no further, Mr. Kim, I'm your man." Oddly enough, that never worked during any interview.

"Boogeda Boogeda Boogeda Aah! Aah! Aah!"

"Let's Rock"

That was just uncomfortable to watch. Ugh.

Yeah. Ouch. That's pretty bad. Especially the delivery.

"Wasted loveGod I wish I could get it back."
