A player substitution at the very end of a basketball game in which one or several low-skilled players (the scrubs) get to enter the game. Generally this happens when the team the scrub is playing for is winning or losing by at least 20 points. Also known as "garbage time."
We're winning by forty points with 30 seconds left. Time for a scrubstitution!

When a sports team, most commonly basketball, knows a game is out of reach and subs in the bench warmers to play out the rest of the game.
Endicott knew the Scots had won so the coach went to Gary on his bench for a Scrubstitution.
