It was Halloween weekend, and the boyfriend and I dressed as Shaggy and Velma from "Scooby-Doo", so when things got hot and heavy and we were half out of costume but still looking like the characters and I went down on him, he blurted that out ...
Yeah. Made me laugh so hard, I couldn't get back to doing it.
I got my revenge later on. After my climax and just as he was finishing his, I added, "Jinkies!" That got him laughing pretty hard.
