To masturbate in public or somewhat public places like a horny orangutan in a hidden corner of a zoo exhibit.
I caught my date doing the corner orangutan under the table after I bent over to pick up my keys...GROSS!

Dude, I caught my roommate corner orangutaning in the shower with my girlfriend's body wash. Close the frickin door next time.
