Gitslap

A harmless technology related prank or message which is presented or delivered in an instantaneous and startling manner and results in an unexpected and profound reaction from the intended target as they try to process what just happened.

Always intended to be the most profoundly savage surprise the gitslap creator can manifest, gitslaps are rarely lame and lacking in effectiveness.

"Bout to send that gitslap to get her mind right."
"That nigga just gitslapped the fuck out yo ass."
"They think it's a game til that gitslap gets they mind right."
