plastic cup party 

A "cool party" in which faggots get together with their "friends" and partake in drinking alcohol (or fucking coors light) from plastic cups and take many pictures of themselves posing with the cups to then later upload to facebook to show everyone how fucking cool they are.

2 girls 1 cup 

The most vile, disgusting, revolting, repulsive video on the internet. It involves two lesbians shitting and vomiting in a cup, then eating it.

Video at 2girls1cup.com. Try to watch it without flinching.

b-cup 

The "best of both worlds" bra size-- not too big, not too small. Look equally great in couture coverage or revealing cleavage.
B-cups are the 'Reese's Peanut Butter Cups' of breasts-- sweet, satisfying, and just the right size.

I don't need any padded bras for my B-cups, I like 'em just fine. I'll be rockin' those girls out on the town tonight.
