When you work in the building trades (so you drive a company van with a lot of cargo space) and the opportunity arises for consensual anal sex with a chick you just met for break on “OT.” Having no place for such act to occur, you offer the back of said van. You then proactively lay a tarp down over all work-related equipment to protect it from any “friendly fire.”
Apprentice: “Dude, why is there a tarp over all of your tools?”
Mechanic: “Sorry bud , overtime last night turned into tarp-time. Wanna see the tarp?
Apprentice: “Uhhh, no thanks.”
