When someone is acting like a jackass; When someone does something really dumb; (ex. trips over chair, says somethin stupid, cock blocks)

Frustration towards someone
---A guy farts and trips over his own feet--- you point a laugh nonchalantly and say "what a cunt piece"

---Friend bumps into you and is egging you to do something which you sure in the hell don't want to do, just say "stop being such a cuntpiece ill do it when i feel like it"

----Someone throws up on you; they're a cuntpiece
