When u fuck a girl doggy style and right before u cum u pull it out and cum on her back, then after u pull out a handful of your pubic hair and stick it on her back
That hairy ass guy that you know who feels too much pride to shave or wax and struts his sasquach-like body around friends and family without remorse. When the issue is brought up socially, the "gorilla back" will often reach back and effortlessly pull out a hand full of the psuedo-pubic hair to shock his company. The women that are turned on by this act are known as "Russian women."
when you're nailing a girl and about to nut, flip them on their belly, rope all over their back, and blow you're pre-shaved pubes across their entire backside. then do her doggy-style while pounding your chest with your fists, making your best gorilla love calls.
last night walked i heard some strange noises coming from my buddies room, i walk in and see my bud chad barking like tarzan with his penis balls-deep in some foreign butthole. gotta love the vietnamese gorilla back"
