What is 'ole Switch-a-roo?
A prank that occurs when a girl leaves the bedroom after sex (to use the bathroom or for any other reason) you hide in the closet while your friend disguises himself as you by covering his body with bedding. When the girl returns she discovers the friend after crawling in bed and getting comfortable.
Last night we pulled the 'ole switch-a-roo on Karen. She screamed when she saw his face wasn't mine.
