To "cock-block" someone. Mostly used in french, and although usually meant to describe a female who lafarges a man, the sexes can be interchanged. This means that the most common use would be for a woman who lafarges a man who is trying to "get with" either her or another female. It can however also mean a woman who lafarges another woman, a man who lafarges a woman, or a man who lafarges a man.
This word can be used to describe actions both with negative and positive results (i.e. if the dude was a big douche-bag, he can still be lafarged).
Also, lafarging someone can be intentional or accidental.
"Dude, the girl totaly just lafarged me. I was so close to hooking up with Cindy, but the lafargeuse came in and started talking about forest fires...MOOD KILLER!"
Boys who enjoy yaoi (a genre in Japan that contains sexual and/or romantic relations between two men); literally translates to "rotten boy"; corresponding female : fujoshi
