More endearing than most derogative terms for skanks. Used when you want to piss someone off and call them a name but you still love them. If they are a skank and need to be reminded sluffin probably wouldn't offend.

a combination of the words slut and muffin. a less harsh word used to call your friends slutty without offending them.
Friend 1: "OMG! I love you girl!"
Friend 2: "AH, I LOVE YOU, TOO! But sometimes you can be a real sluffin!"
Friend 1: "Yeah, I totally know. I shouldn't have hooked up with those 4 guys last night!"
