to roll up your collar to look preppy or badass
We COLLAR POPPERS are so badass.
An act that involves pulling your collar up and over your neck. Despite looking moronic, and defeating the purpose of collared shirts (looking somewhat respectable), this has somehow become a fashion trend.
John Smith: Wow, look at that moron's collar pop.
Me: I really wish clothing companies would start writing 'douche' on the inside of collars. Maybe being labelled a douche by their own clothing whenever they pop their collars would be enough incentive for them to stop.
