Boosting may refer to any of the following:
1. In general, to boost or boosting with a computer refers to the act of increasing the performance of a computer. For example, you can often boost the performance of a computer by replacing a traditional hard drive with an SSD.
2. In computer gaming, boosting is the method that allows a player to look over a high object or jump onto a higher object by jumping on other players while they are crouched down.
Although this is part of the game, many players consider this technique cheating since it usually gives another player access to places they shouldn't be and usually gives them an unfair advantage in the game.
