Hotel Muffler 

Using hotel towels to muffle your farts while shacked up in a hotel with a strange woman.

When you are in a hotel room with strange woman about to get blown but you need to fart. You go into the bathroom, grab all the towels, hold them up to your ass and fart. Hence a hotel muffler. She suspects nothing unless she uses one off the towels to clean the gizz off her face
