The act of the granny stain involves a well matured female wearing adult diapers. Before sexual activity takes plac, the gilf unleashes a slick wet shit in the diaper. The male then removes the diaper and places it on the grannies chest at which point he mounts the grandmother in the missionary position and proceeds to smear the poo all over grannies chest with his chest.

The most devastating insult known to mankind. Easily repels all insults, including "your mom gay" and "your dad lesbian" and will absolutely decimate your opponent's pride as well as their will to live. Due to its destructive nature, it should only be used in grave situations.
Bob: Your mom gay!
Jim: Your dad lesbian!
Bob: You leave me no choice, Jim
Jim: No! Don't do it!
Bob: your granny tranny
*Jim collapses from cardiac arrest*
Jim: Your dad lesbian!
Bob: You leave me no choice, Jim
Jim: No! Don't do it!
Bob: your granny tranny
*Jim collapses from cardiac arrest*
