Person A: So this one guy kept asking me for nudes and tried to defend himself by saying it’s just the natural biological desire to see the naked body of a woman he thinks is beautiful.

Person B: Wow, he sounds like some sort of Darwinian Neckbeard

Mike: "Nope. Not happening. It's Jaunty neckbeard January man. I have to complete the challenge, ty very much."

Steve: "Who the hell is Ty?"
