Bluefags usually talk about their eyes to distract other people from how ugly the rest of their face is.
Note: Bluefags represent an extremely small percentage of people with blue eyes. Having blue eyes does NOT make you a bluefag; bragging about them does.
Regular person: Brown.
Bluefag: Well, my eyes are aqua-blue with green speckles and a yellow outline.
Regular person: Shut up, Bluefag. You just want to talk about your eye color because you're trying to hide the fact that your face looks like crap. Your eye color may look OK, but your eyes themselves look terrible with your face.
