thug snap

When normal snapping with your thumb and middle finger is too stupid you flick your stupid fucking wrist around until you get 2 fingers to click, or "snap" against eachother. Usually done to show "thug respect" but can also be used a threat if done correctly. Also if done consecutively, it can sound like you are fapping.

Yolo McSwag: Man that shit is fuckin' dope! *thug snap*
Me: Shut the fuck up swaggot. *threatening thug snap*
