This little trick is best used in the 4 player deathmatch, if you just so happen to get knocked out of the game early, there is still a way to nail your pals. If you very quickly tap on the L1, L2, R1, R2 buttons you can charge your glove and explode. This can be done as many times as you like. You will not get any hit points for this, just a bit of satisfaction.
