San Francisco Fish Hook
When a person shoves their index finger all the way up the other person's ass and curls it in a "come hither" motion, resembling a fish hook. The Hooker then lifts the Hookee by the hook in their ass, suspending them like the Golden Gate Bridge by their asshole.
Bill thought he was getting a prostate exam, but was surprised by the doctor's unprofessionalism when it turned out to be a San Francisco Fish Hook instead.
