Trans-donker
The act of donkey punching a man, causing his testicles to retract into his abdominal cavity; then quickly tucking his penis between his buttocts and flaring out his foreskin into simulated labia before he fully regains consciousness.
I gave my dad a trans-donker the other night. When he stood up he reminded me of Buffalo Bill from Silence of the Lambs. He has not made eye contact with me since.
