I am trying to come up with a good derogatory nickname for Fannie.  How about :  I just took a Fannie.  I feel better now. I got rid of all that waste.  Or we could say:  I just Fannied - farted.  Or we could say:  Man I feel sick.  I think I am going to Fannie - barf.   Hey Man you just pulled a Fannie - you messed up.  You Mom is a Mother Fucker - now it is Your Mom is a Fannie Fucker.  Oh Man you're Fannied -or You're fucked.   Sorry for the F Bombs but I am having so much fun thinking of all these new names.
