pop your collar 

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."
