Cadaviar is just another name for potted or canned meat like meat pâté or deviled ham.
It is a play on words of cadaver (dead body or corpse) and caviar (salt cured fish eggs).
I went to the store to buy some cadaviar for the party.
A sluth is two words combined. Slut and sloth. It generally means a visually attractive yet highly unclean prostitute, as in, she is so lazy, she never bathes or cleans herself. She is thought to be carrying multiple venereal diseases, to be on crack cocaine, and her home is believed to be so trashy with filthy garbage that roaches and flies are everywhere.
"Jack, I went to club Mixer last night. Do you know that girl on the dance floor with the silver 2-toned belt ?"
"Orange dyed hair ? Yeah. You don't want to mess with her. I heard from others that she's a real sluth."
Predult is a smaller word for, "Prior to being an adult."
It is normally used in an insulting term to show someone who is 18 or over and is not acting their age by being interested in childish toys or ideas, and that instead of acting like an adult, they are acting more like a teenager, tween, or even a child.
(At a party) "Hey look ! They've got boxes of LEGOs in this one room !"
(responding) "That's for their kids. Stop being such a predult and get yourself a beer already."
Farting, except with sparkles. You can see this in the two movies, "Angry Birds" and "Trolls."
"Say again how sparting on me creates camouflage !?"
A frap is basically a loud fart. It can happen when someone is trying to quietly fart with others around but is unsuccessful and it is heard quite clearly by them.
"Jeremy totally frapped during homeroom this morning ! Everyone turned to stare right at him."
Another synonym for a man's testicles.
"Dude, I went out with Kathy the other day. We got busy back at her house and she totally sucked my fun plums while I whacked my weasel."
Texting abbreviation for, "How did you do that ?"
"I almost got caught in the boys locker room, but then I made myself invisible."
"HDYDT ?"
