Similar to, but not to be mistaken for "eye liner", it is the rimming of the male eye with usually a
charcoal black color, and done
voluntarily. Usually done by rock stars, emo kids, and more recently hipsters, it is a word used to masculinize a usually feminine product, thus making it more acceptable, at least for themselves. This is the main purpose for
calling it by something other than simply eye liner, a term used by either women, men who cross dress as women, or men who never actually wear it themselves.
It can also be used ironically by a second party, making fun of those belonging to the aforementioned groups, aka emos, wannabe rockstars, hipsters, etc.
Girl: Hey squirt, will you let me borrow some of your
eye liner?
Boy: Its not eye liner! Its Guyliner! ...MOOOOOM!! Sissy's stealing my things again!!
Jock: I bet
you don't attract as much poon as me with
your stupid Guyliner! Ah ha ha!
Emo: *cries softly as he Tweets about his problems*
