a wayback
A old-school crackhead who still shoves that god-awful crack in his mouth like it's the last day on Earth.
My uncle is a wayback. He still does that crack thing every day, even though he's got a beard like a raccoon.
My cousin’s wayback cousin came to visit. He brought a bag of crack and a hat that smelled like a dumpster.
My neighbor is a wayback. He used to be a cop. Now he's just a crackhead with a badge.
