What is this trick called and how to do it

[sniper]

Can someone tell me what this trick is called and how to do it?I think its just a burnout or does it have a name?I assume that you just lean forward and hold the front brake in a bit and give it some throttle.I have tried it but i think im holding my brake in too much cause i stall it all the time and if i try not to hold it in so much i end up having to change gear.Anyway have a look.

they aren't hard, just pull in the front brake a bit and rev the **** out of it.
