The small, remaining ends of marijuana cigarettes are called roaches. Avid marijuana users often save the ends for a rainy day, as they have concentrated amounts of resin and THC. "Roaching" is the act of gathering these ends, smoking them, and getting extremely high.
We ran out of weed, man, so we're roaching.

Roaching, to out a Joint near the end in order to smoke later/save. -Not- to be confused with filters which are created by rolling stiff paper and inserting it into the end of the Joint.
"roaching a joint with a filter in it is stupid as it can be smoked all the way down"

when someone sneaks behind other people's backs to manipulate them for their own benefit. Like cockroaches, they run whenever the lights are turned on. A couple of people in particular were my inspiration for this term.
when someone goes behind your back to try to turn a situation to their advantage, that person is roaching.
