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."

Brain-to-Head ratio

The ratio between your brain and head. Small brain/big head = low BtH
Big brain/small head = high BtH
Girl 1: “Lmao did you see Stephanie’s BtH?? It’s like.. so low!”
Girl 2: “I believe emotional intelligence is more important than the size of ones brain. Being kind is what truly matters.”

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.
