A trend started by Michael Jackson in which the collar on a polo shirt, for instance, is unfolded and kept straight, facing upward. This has continued to be a trend for preps, as well as "rich ghetto people."

When a male is masturbating and another moves up unbeknownst to the masturbator and then strikes the testicles at such a time that the masturbator is just beginning to ejaculate.

The side-effects may include vomitting, depression, and penis explosion, which can in turn lead to death.
I have always wanted to pop a collar because everyone always masturbates at my house for some reason and I'm getting sick of it.

Yesterday i walked in on Theo masturbating and I popped his collar. Good thing he was already at the toilet because he threw up all over the place.

When you pop your collar, you reach up to the shoulder of the correspoding arm or across the chest to the opposite shoulder, and, using your index finger and your thumb, you pull up on the shirt and let it "pop" down, hence the phrase. It is perfectly acceptable to pop your collar whenever you have accomplished a great, admirable feat, such as busting a sweet dance move, pwning the entire opposing team by yourself, or to establish your extremely high playa factor.
Derek, obviously outmatched, kills all 4 of his enemies alone. Derek pops collar, and TJ holla's "Thats right, pop your collar home boy!"

To flip your collar up on your polo shirt. Very common practice for guys in fraternities and other college-age preppy types. The guy who does this is often referred to as "that guy."
Ronald could never convince anyone that he really popped his collar for practical neck insulation and was not in fact "that guy."
