Definition: A 'rebuy' is a term in poker used in two ways:
1) In a poker tournament, there is often an option to "rebuy" back in to a tournament if you bust out or your chip stack falls below a certain number. There may be an option to rebuy in anywhere from one time to an unlimited amount of times.
2)In cash games, if you lose your entire stack or most of it, you may choose to "rebuy" back in with more cash and keep playing.
