1. v. to eat a girl out while she is on her period.

alternatively,

2. v. to throat-fuck an individual to the point that your balls slap against their face with such voracity that their chin becomes chapped and red, thus giving them a "crimson chin".

Daringly, these two actions can be performed at the same time to result in what can only be described as potentially one of the leakiest sex acts.

The Crimson Chin is the sexiest and hottest chin in the universe. It overpowers Jesus's gay powers. The crimson Chin's sexy dimple hole is the highest power in the universe, overpowering the world's longest dick by a astronomical unit. If you get close to it, it will spray you with magical gay period juices out of its bloody clitoris. The dimple pit is bigger and deeper than your manly vagina. If you come too close than it will douse you with dead asian Hiroshima people's blood, thus why it is called the Crimson Chin.
Oh, his Crimson Chin is so sexy!
