Whenever a female is hella sprung off your ass and constantly won't get off your nuts. She needs your attention and won't stop texting, messaging, or calling you.
"Man, I've only been seeing this bitch for a few days and I got her swangin' from my ballsackalready!"
swangin cunts is a phrase used when describing how dupesly rad people are, and how much you love them, this is the highest form of praise in the entire universe.
