A person who hangs around the streets and partakes in activities not viewed as normal from "normal" people. Such activities may include:
-Doing drugs, usually meth but can be other drugs ranging from weed to fentynal.
-Acting like a crazy homeless person.
A tweeker is not always homeless or unemployed but in most cases this is a fitting description.

Hey dude, why are going to bid $40 for that ipod on ebay when you can buy it now at tweeker bay from cranster tony down the street for $10?
The amazingly stupidlogicpeople use when they're drugged beyond belief, but still want more.
Tweeker1: I'll let you punch me in the face for just one hit of your joint. Tweeker2: That sounds like a good deal to me. Rndm Guy: That sounds more like TweekerLogic to me....
