Breastphyxiation

The act of suffocating someone with a large pair of breasts, usually a D cup or larger. This usually occurs when someone tries to motorboat a girl and it goes horribly wrong, causing him to asphyxiate within the girl's breasts.

John: Bro, did you hear about Dave?

Nick: No, what happened?

John: He was trying to motorboat some hot chick with a huge rack, but got lost in there and died.

Nick: Dude... *shakes head*

John: Yeah, the coroner said cause of death was accidental breastphyxiation.

half-shitted grin

A grin for one of those moments where you say or do something that is so unbelievably dumb, the only thing you can do is grin in a ridiculous manner. Bear in mind, the said action is literally so fucking stupid, no normal grin can convey the amount of stupidity your brain just expressed. (i.e. The face you make when your brain has a severe case of the shits.)

Sam walked into her kitchen and saw her boyfriend butchering yet another cow on the table they ate dinner from. When he noticed the angry look she gave him, all he was capable of was a half-shitted grin. This was the third time this month.
