Scott Pioli tee shirt tucked in his pants... Not that Pioli needed any help looking like a bald, fat, prick, but tucking-in a t-shirt makes him look like a giant douchebag, as well. And sorry to offend, because I'm sure that there are posters here that do it too, but it just makes you look like a giant, ridiculous, douchebag. Anyone under 40, and any cool people over 40, are talking behind your back at you if they see you with your t-shirt tucked in. It's a t-shirt for gods-sake, loosen up a little bit. Relax, live a little, people don't think you're a slacker or a stoner if your t-shirt is untucked, they just don't think you're a giant d-bag. That's all.

When did this become a thing?

Around the mid-to-late 1960's.
