The stinkyty is done when one individual is upside down in position and another individual puts there penis in their mouths and testicles on each nostril. One participant will then cum in the others mouth while the other is sniffing the testicles.
I gave Conor the stinkyty last night and oh man was it a blast!
Another way to create a stinky Hitler is after sodomy, you transfer the shit by dotting the upper lip under the nose with the head of the shit covered penis
