BTH 

Black Tar Heroin; aka H, Ron, Tar, The Black. It is a substance varying from powder to a sticky tar-like consistency with color ranging from orangish-brown to black. It is consumed by placing a small piece of BTH on the dull side of tin-foil, and administering flame to the underside of the tar, in an attempt to heat the substance substantially enough to phase-change to vapor. The user leads the gooey trails with the lighter in front and follows behind with a straw in mouth. This process is also commonly referred to "Chasing the Dragon."

Yo you wanna chase bro? I got that BTH boy, that good shit man. Lets smoke some shit tonight bro.

a) an abreviation for the term "big time huge."

b) a poor attempt at creating a phraze similar to BT for big time. the phraze BTH has caught on in popularity due to the immense amount of stupidity that it entales.

This is what Wikipedia wants you to believe.
Unfortunatley, it stands for British Torture House, and is exactly what it says on the tin.

"So Jane, what school are you going too? I'm going to Sale Grammar (another hell hole, but considerabley better)"
