The Tennessee Horseshoe
While performing intercourse on your significant other, you unexpectedly rear like a horse and neigh at the top of your lungs. When he/she questions your horselike antics. In the heat of the moment, you strike her in the head with a horseshoe and eat hay off their unconscious body.
Yee Hah. I just found out dad cheated on me with my sister so I did The Tennessee Horseshoe on Ma'.
