look up any word, like sex:
 
1.
A verb that describes the action of silly people (mostly cops and firefighters) who like to close the back doors of a mutual aid ambulance for the EMTs and then slap the back doors, usually twice in rapid succession. This is supposed to tell the out-of-town driver (at the front of the ambulance) that they are now clear to leave the scene, instead of listening to the trained EMT who is IN the back of the ambulance and actually knows when it's okay to leave.
I'm sick of getting ambuslaps every time we go to a mutual aid car crash.
