a term that can be used in the place of bump that, screw that, who cares, or other related terms. to properly execute a "keep the change," one must witness something that requires such a statement, then imitate someone jerking off and extend your hand forward opening your fingers as if you ejaculated. this hand motion must be done along with saying the words "keep the change."

the hand motion is demonstrated in Superbad following the shootout between Slater and Michaels. Michaels performs the correct hand motion, but does not say "keep the change." it is acceptable to forgo saying the actual words, but it works much better if spoken along with the hand gesture.
