Not to be confused with the "Hot Carl", "Rusty Trombone", or the "Cleveland Steamer" the Dump Truck is the act of wrapping one's head with seran wrap and allowing a partner to defecate on said seran wrap. The point of this is to watch the "Dump Truck" dump it's load.
Little Tommy went "dump truckin" with Susie but she forgot to cover her hair!!
