An audio exclamation often used during the process of throwing or launching a hard object at an unsuspecting victim. The one exclaiming "yingbat" often times turns around after throwing the object while one of his cronies watches and observes the victim's horrified reactiong after being struck.
Joey: Hey check out that one guy. Someone should definitely throw this unopened can of soda at him.

Landon: Where is he? Oh wait, I see him...YINGBAT!

Joey: Dude, it hit him right in the face!

Everyone around: (Hysterical laughter)
