Double reverse blumpkin

When a person is upper decking a toilet and another person is shitting backwards on said toilet giving oral sex to the person doing the upper decking.

The only reason I like house parties is pulling the old double reverse blumpkin before I leave.

This card is currently the most devastating weapon out there.

The speciality of this card:

• It has no expire date as long as it's in good condition
• For this item to take it's action, it will react in an instant, in fact, even if an atom bomb is right above your head and you pull out the UNO Reverse Card, it will instantly ricochet to where it originally was.

Me: pulls out UNO Reverse Card "Not today sir!"
Cashier: "Aw man, you got me there. Alright, next!"
