Definition: Normally, when one finds something disgusting or distasteful one usually will 'gag' in revulsion. If it is something excessively disgusting or distasteful, one's fanny may gag as well.
Example:
"Sorry Miss, I couldn't do my homework last night because I was masturbating furiously"
"NATHAN! Don't make my fanny gag!"
"Sorry Miss, I couldn't do my homework last night because I was masturbating furiously"
"NATHAN! Don't make my fanny gag!"
