thot collar

When someone has cut out a triangle from a shirt, generally a t-shirt, exposing the chest but leaving the neckline hem. This makes for a messy, hemless cut into the tip of the triangle, with a perfectly intact neck, giving the impression of a collar. This style is more common among thots than any other demographic, as other demographics either take away the collar to leave a more fashionable cut, or pre-purchase a shirt with a boob window to have a clean hem.

Thot: So, they didn't have, like, a nice version of my home team's t-shirt, so I taylored it myself. Neat, huh?
Thot's friend: Oh, honey...I'm so sorry. You've created a thot collar for yourself.
