Gamer vents

A natural evolution for a gamer who sits for prolonged periods entertaining their Twitch chat.
Medically known as 'Pilonidal sinus', this occurs when you're flat on your ass every single day. The body begins to develop sinus', or arguably 'vents' that a gamers butt requires in order to breath properly, like a whale that's been bottom feeding for an age.

That Ninja guy must have mega gamer vents, he's on his ass gaming all day everyday!
