In Modern Warfare 2, a person or group of people who use Tactical Insertions to their advantage, go to a rarely-used place on a map, set the insertions, then continuously kill each other to get a free nuke or a bunch of free headshots. This is considered complete and utter cheating and is commonly rejected by professional players. MW2 pro "Sandy Ravage" has a series on YouTube called Booster Justice which is him killing boosters to no end.
Yo, want to boost?" "No, I don't cheat, you booster.

When used in video games,a booster is a player who gains points by unfair means.A booster will usually have another booster with him,or sometimes go into a lobby with a game full of other boosters.The most common ways of boosting involve one player(or one team)standing in one spot the entire game while the other player(or other team)kills them for points.Thus,getting points and leveling up faster without doing any work at all.It would be like doing no work,and getting payed overtime.
Booster 1:Okay,stay there and don't move.

Booster 2:Okay.
Booster 1:*Shoots*
Booster 2:*Dies*
Booster 1:Alright I ranked up.Now you do the same thing.
