Top Definition
To bullrush an unexpecting friend or enemy, and violently chest-bump them into a hard object such as a wall, locker, or other person. No hands are allowed to be used, chest only. While approaching one's prey, they must use advanced stealth-like movements, blending in with the crowd until the moment arises, then move in for the strike, announcing "Powshk!" as they make contact.
"Dude watch me wreck this kid"
creep...creep...creep...
"POWSHK!!!" (Victim flies through a concrete wall)
"haha i love doing that"
