Pliffing is considered to be the most embarrassing forms of laughing. It involves laughing and pissing. The laugh starts abruptly before you have a chance to save it....you pee everywhere uncontrollably and for some unknown reason it is still funny. aka Dan Nicole
My friend made me laugh and I started pliffing my pants and continued to laugh like nothing even happened.
