Cockboi
A guy obsessed with his own cock. He can't keep his hands off of it and likes to take it out in public and show off. When he's with friends, especially when alcohol's involved, he's the guy flashing people and pulling down other guy's pants. Proudly or secretly a rabid masturbator. He'd pick jacking off over sex any day. No guy or girl knows how to work his dick as well as he does. His libido is so high anything can set him off.
