The Ghetto Jump (which was named by Kip) is a move used to achieve greater jump heights than usual by means of using a wall and holding L to lock the user's veiw. When jumping, press against or just barely touch a wall. There are different variations of this jump, such as holding L for a certain amount of time or jumping into a crack to force yourself upwards.
The Ghetto Jump is most noticable when the user executes this trick underwater, while still hindered by the affects of water. Extremely high distances have been recorded. Some single jumps have even matched the height of regular space jumps.
