Usually said after a noun, is sex means "It's so fucking good." the word came from the similarity of the great feeling you recieve when having sex. So when you say "________ is sex" it means, that whatever it is is as good as sex gets itself.
Cheese is sex!
(Insert band) is sex!

when you shove your dick into a lava lamp because your lonely as fuck
by Jerry the wanking dolphin December 16, 2018
Sex is the acronym for the way humans are created. S stands for Super, E stands for extraterrestrial, and X stands for Xenomorphing. So sex is Super Extraterrestrial Xenomorphing. The way it works is the storks deliver the baby to the mom. The baby is created by crushing high energy mass, and the rest ends up in the mom's belly. The mom goes to the hospital so they make sure that she doesn't drop the baby. And she also had to scream really loudly for the storks to know where she is.

"I wish I was getting sex tonight instead of looking it up on Urban dictionary..."
by blahderdash April 14, 2009
to fuck, to screw, to bang, to reproduce, to copulate, to pork your lover, to booger my bed, to hump your honey, to get laid, to lay some pipe, to hide the salami, to slam (or to get slammed), to burry the bone, to stuff the donut, to moisten the carpet, to dine in the Y, to munch on the rug, to physically express shit, to slam the hen, to shoot the sherbert, to whack Willy Wonka into Wonderland, to yodel in the mighty fairy-infested, stinky, and yeast-infested canyon of love. There are many kinds of this, like dick in ass and dick in vagina, dick in mouth or vagina in mouth. It expresses pleasure for both men and women.
"I got fucked, John."
"Realy, by who?"
"Stupid question pussyhole. It was us."
"Yes, sex babe."

Where is your brain? Oh, that's right... it doesn't exist! I cannot believe you are retarded enough to look up "sex" on Urban Dictionary. You can try to get it, but you will never have it, for your micropenis can and will scare all women in a 70-mile radius. Fuck off and watch Pornhub instead. Your school blocked it? Too bad.
Pornhub will be the closest you'll ever get to scoring with a woman. You will never have sex. You will forever remain a virgin. End of story.
