boston buttercup 

When a male screams in a Boston accent while having a rod painfully slammed into his ass, usually occurs during the hazing ritual of some Frat's. The buttercup demonation is still unknown, however, when asked why it is called "buttercup" most victims flee away, screaming in terror.

"Hey Bobby, would you care to rush Gamma Alpha Yeti with me? I promise you, we don't perform the Boston Buttercup on our rushes!"

The Reese's peanut buttercup method 

The Reese's peanut buttercup is the act of trying to go to third base while your parents are home. In order to do this, you must reach into the girls pants and try to finger her while she lies on top of you with both your clothes are still on. This follows after hooking up and boys desire to go farther. The results may vary but it still contains enormous amounts of awkwardness. However, this method can be very useful because you can brag to your friends about going to third when, in fact, u haven't gone past 2nd.

Girl: wanna hook up?
Guy: nah lets go to 3rd this time.
Girl: No!
Guy: fine how about The Reese's Peanut Buttercup method?
Girl: Perfect

Princess Buttercup 

When a guy ejaculates onto a girl (or guy's, we're not discriminating) forehead, thus creating a sort of tiara, while simultaneously buttercupping them (farting into their hand and throwing it into their face). This turns the girl (or guy) into a Princess Buttercup. It is also not unheard of for the farter to be dressed as a moose during the act.

Albert Einstein: Energy equals mass times...
Edgar Allan Poe: Shut the fuck up, Einstein. Galileo, you Princess Buttercup Madame Curie, yet?
Galileo: Fuck yes. Her forehead was sticky with sperm and her face full of stink, just like my grandma's used to be.

Edgar Allan Poe: That's hot.

Galileo: Yes.
Edgar Allan Poe: Imma try that with Lenore.
Galileo: Indeed.
Albert Einstein: Did you dress up like a moose.
Galileo: Yep. Did the full Princess Buttercup.
Albert Einstein: Hardcore.
