look up any word, like pussy:
 
1.
When 2 people cheat on their boy/girlfriend by cuddling w/someone else. And end up doing more than that...
"So is she still with Jake?"
"No dude. We all watched a movie last night and she was cuddling with Sean. But they were doing way more than that, they were sluttling!"
"Gross."
