LaughGasim 

A phone prank when you get someone to do things on a public netcam somewhere in the world with them not knowing their being watched by 100's of people from around the world LIVE.

That hooker had no idea we could see her on that netcam in New York City. When she got mad about being stood up and threw that fit it was so funny. We all had a good LaughGasim.
