A method of smoking hash, oil, or hash oil by which a small hole is made near the base of a glass or plastic bottle large enough to allow a the lit end of a cigarette access without touching the bottle.

Next a small amount of hash or oil is placed on the lit cigarette, the lit end of which is then placed inside the bottle, allowing it fill with smoke.

Once all the hash or oil is burnt off, the cigarette is removed, the cap of the bottle is removed, and the smoke is inhaled through the mouth of the bottle.

Also see bottle toke and BT ...

BT is short for "Bian Tai" in Chinese.
Bian Tai used to mean homosexuality or someone is innormally addicted to something(esp violence & sex). But now it's widely used among youth like a tag for anything that looks too good or bad.
Tom adjusted the tint on TV so that all the people are green, and insisted:"I like it that way."
ppl:"You're too fucking BT."

Blessed Trinity Catholic High School a school designed to torture students with its draconian disciplinary system. See PDA for one of these rules. Uniforms must be impeccable and faculty often checks to ensure girls have the proper skirt length. Additionally, boys must wear socks of a certain height. These and many other Nazi like rules define BT.
Excuse me your skirt is too short! We don't allow that here at BT!
