Hahnjob
When a guy shoves his fist up a girl's butt and pumps it like a toilet plunger until she squirts.
My cousin did a Hahnjob on my mom and she cried tears of joy and shame.
I saw my uncle do a Hahnjob on a waitress and she left a 50-dollar tip.
My friend's girlfriend does a Hahnjob every morning before work, and it's her alarm.
