Tom Bekelaar

The type of person who uses a lanyard for sexual pleasure, and sends nudes from angles which makes their balls look massive, and their penis tiny.

Molly: Hey Christopher get a look at that Tom Bekelaar!
Christopher: Holy crap that lanyard is tied tight around his balls!
Molly: They're going to explode! They seem bigger than someone who'd never had a wank before!
