Awkward burnout

Hey guys the other day i was up at my parents house and my dad said hey you should roast the tires before you leave and well how can i say no to that..so i hit it up..well and awkward yet interesting thing happend.. Did my normal burnout technique hit the brake and throttle up well it started to roast them and the proceded to push my front wheels locked across the ground. Whats that about.. Kinda makes for an imbarassing burnout doesnt do it all the time just then left 4 black marks down the street i mean the fronts where just locked solid just pushed them acroos the ground? And suggestions..to me i think i just have great traction and probably need to lay some water down.. What do you guys think do gears have anything to do with it? Had 456 but have 323 right now
