A pipe of which Crystal Meth is packed into and smoked out of.
Jib being meth, and whistle being the actual pipe. If the Jib Whistle is reefed on too hard it may make a mock-whistle sound.
: Hey Nick, I can hear you playing your jib whistle over there!
: Aw fuck son, you know i'm hooked! Just let me get HIGH!
: You bloody Chappoes!
