when one loves the smell of their farts yet doesn't want (or is too lazy) to fart and then lean over to smell the area that they farted in. Instead, they can make a cup out of their hand and fart into it, close the "cup", and bring it to their nose, where they can open it and sniff.
That person loves their farts. Dude, they are the master of the cup and sniff.
A protective cup is an almost triangular piece of equiptment that boys wear over their balls to protect them. They are sometimes used in bondage for girls (or gay guys) to feel and stuff.
I was the target of an attack of these assholes in gym class. He took off his protective cup, gave me a stinkface and then made me wear his protective cup over my face. He taped it there and then he spanked me. The cup was over my mouth so i couldnt scream.
A breast size that is slightly above average. In America, the medium to larger C Cup sizes are the optimal range of breasts, as they strike a happy medium between too small and too large to adequately grope. By Japanese measurements, however, a C is the equivalent of an American small B, so As are something truly pathetic in Japan.
1: Damn! That bitty got perfect titties!
2: I'd say she fills a C Cup pretty nicely.
