THE RULES - If You Wouldn`t Eat Soup Out Of Her Ass Then You`re Not A Fan Of Soup - University Comedy

You may have heard people muttering FML and wondering what the hell it means.  Well it means F*ck My Life.  But where did the expression come from. 

See the below montage from Superbad to understand.

There is even a site dedicated to FML. I was told about this site 5 times in 2 days. Spreading like a bad viral STD indeed.

Some slight variations:

FYL - F*ck Your Life

FOL - F*ck Our Lives

and etc.
