Genital Mate 

The genital equivalent of a soulmate. When you meet a member of the opposite sex and as soon as your genitals touch for the first time, the clouds break, a ray of light shines upon your crotches, choirs of angels start to sing and the world around you begins to crumble.

“Dude, I banged this Colombian chick lately, I think I found my genital mate! The sex was out of this world and we both came like five times in a row, it was absolutely ridiculous!”

gentlesir 

Usually young white beta-males who live on Reddit or 4Chan. They wear fedoras with t-shirts. They open doors for women ("m'lady") or do other nice things not because they're polite people, but because they want to get laid.

Also related: talking about getting friend-zoned, loving V for Vendetta, libertarian politics, thinking they're the smartest person in the chatroom, basement dwelling, etc.

The gentlesir tipped his hat to m'lady and opened the door for her. She was just a random bystander and walked in without acknowledging him. He muttered to himself about how rude women were these days before checking the Reddit thread about anarchism.

Emma: "Wow really? Scissoring?!"

Jessica: "Hell yeah!"
