Top Definition
An emergency exclamation used to alert friends in the immediate area of the necessity to leave RIGHT NOW with no questions asked, usually because you have just comitted a crime or done something illegal or that you will be in very big trouble for. Like "bounce", only much MUCH more urgent.
"Dude, why did you call 1, 2, 3, bounce? I was getting ready to buy a manga."
"Because I puked all over some books in the C++ section."

You should never yell 1, 2, 3, bounce unless you really mean it.
