STP is an acronym for Surplus Tit Packets. Surplus Tit Packets are formed when women wear a bra which is quite evidently too tight/small, combined with a form fitting shirt, such that parts of her breasts which can't be adequately contained by the ill-fitting bra create a spill-over affect.

It's bad enough that the girl had FUPA, but she also had STP; she was bursting out all over.

STP is, as we learn in science class, is short for standard Temperature and Pressure. But what it actually means in the hip world of today is Scary, Terrible Puffin.

"Oh man, did you see that STP?!"
"Yeah dude it's radioactive but embroiders!"
"Whoa."
