The technique of catching a stanky fart in ones hand and then releasing it under someones nose.
When he started talking shit about my gas I had to buttcup that bitch Russ.
Ah the most bitchy powerpuff girl and the most fabulous. Doesn’t give a fuck and is a badass.
Guy: You see that girl, she’s a buttercup.
a) This is a sexual act in which the man shits in the girl's mouth, makes out with her, and have each other swallow as much shit as possible until either of them vomit. The girl and the man will spit the mixture of vomit and shit into each other's mouths while making out until either one of them slips up, hopefully spilling the vomit onto the man's penis. Once this happens, the girl must give him head until he ejaculates in her mouth. The girl will spit it on his penis in disgust.
b) The Powerpuff Girl of the same name. Has freakish body proportions, much like her two sisters.
a) No explanation needed
b) Using their ultra superpowers, Blossom, Bubbles, and Buttercup have dedicated their lives to stopping crime and the forces of evil!
When someone punches you in the asshole. Not fisting, being buttercupped is not meant to be sexual in anyway. Only the pains of Satan are intended when someone buttercups another.
Jason: Dude why the fuck did you just buttercup me?!?
Michael: I buttercuped you because you stole my wallet you fuck!
A male child, usually in his twenties, who refuses to get his act together. A spoiled brat, who thinks his parents, and everyone else, are obligated to support him forever, because he's special, and exists. A freeloader.
Mike's a buttercup. He never pulls his weight...
A beautiful girl whose body is perfect in every way except she has a flat chest. Everything on her body is immaculate "but her cup" size.
"Dude, Krista is smokin' hot. If she wasn't so flat, she would be absolutely perfect."
"Yeah, she's a total buttercup."
A girl that you build up just to let down.
Why do you build me up Buttercup, just to let me down and mess me around
