Roach...is the phantom alt/evil genius , who lurks everywhere but is known only by but a few distant ones.
Always watched but never seen.
The minuteman of activism.
worship him, respect his unbounding knowledge, revere his undying compassion, and fear his wrath.
In the beginning , there was Roach...

everything else followed.

You remember that guy I dated three months ago? I told him I wasn't interested and ended it with him. Well, he just text me and asked if I want to grab drinks with him tonight. He's such a roach - he just won't die.

england:slang term for rolled-up piece of cardboard put in the mouth end of a joint to catch tar which is produced by tobacco rolled in the joint.

america:usually means the end of a joint which can be re-used because there's still some weed in it. this occurs because in america, joints aren't rolled alot with tobacco and so don't need a filter.

not related to weed: a small freshwater fish.

A roach is the reminisce of a smoked joint. Once a J becomes the roach it can become very difficult to hit and it is best to usually give it to the "roach master"

A roach master is someone who can hit the roach no matter how small it gets and commonly sells cigarettes for a dollar.
Parker: "dude i don't think this joint is lit anymore, its the roach"

Lev: "dude give it to the roach master!"
