street pusher
slang Low-level drug dealers who sell directly to customers in public, as on street corners. I was a street pusher for a number of years, as it was the only work anyone could get in our neighborhood at the time. You're never going to wipe out drugs in this city if you're only arresting junkies and street pushers.
