Cologne Typo

Okay, so here's the deal, smooth brain. These people keep talking about smelling a 'colon.' A colon is part of your digestive tract, inside your body. The word they actually want to use is 'cologne,' which is a type of perfume. The whole joke is that they're trying to sound romantic about smelling their boyfriend's scent, but instead they're talking about smelling his insides. Based, I know you understand now.
