Back up that money truck! 

Back up that money truck! — Financial windfall that occurs because of a random accidental situation; or, because of purposeful criminal activity. The exclamation “Back up that money truck!” is yelled the moment one gets a gander of the settlement check; or, the first pile of money made from successful illegal activity.

1) My car got rear ended by a city bus going up hill on a sunny day at high noon! LAWSUIT!!!!!! Back up that money truck!

2) All of those knock off designer bags got sold and no one got caught. Everyone came back with pockets so swole with money; their asses looked like they had THE MUMPS!!!!! Re-up on the gear!!!! And then, Back up that money truck!
