chin spinner 

A vicious knockout punch to the face, often spinning the recipient's head a full quarter-turn.

The fighter in the blue trunks was clearly demolishing the fighter in the white trunks until he got hit with a haymaker chin spinner. Fight was over!

Chin-Stinner 

The action of "cum blasting" your own chin (and/or face) in the act of masturbating (jerking off) and reaching a powerful and sudden climax.

"dude, I full on gave myself a Chin-Stinner this morning. Caked myself"

"I was sent this Snapchat of this guy wanking himself off and he cum all on his own face. It was a beautiful Chin-Stinner"

coinspinner 

1. Noun: Sword (in the epic series by Fred Saberhagen) which made its bearer lucky. Not lucky like with the ladies, but mad lucky like someone attacking him would trip on a piece of paper and be impaled through the eye by a randomly bouncing pencil lucky.

Dave slept, but Coinspinner protected him by generating (weeks in advance) an odd strain of ecoli which laid dormant in his attackers stomachs until they tried to attack... they were then seized with the exploding hershey squirts and terminal technicolor yawns.
