look up any word, like sex:
 
1.
When someone on facebook constantly has the urge to just constantly post everything they are doing in every second of the day.

2.
A group of 2 or more males that write regularly on eachother's facebook walls phrases such as "Hey Cutie", "Love Ya", Hey Sexy"...
These homosexual phrases are usually followed up by several cyber smiley faces and/or hearts.

In most cases this Facebook Fag conversion indicates slightly or full blown sexual interest in the male that they're are flirting with on facebook. Basically, they are truly fags and NOT trying to be funny.

They could easily text this gay conversation but they choose to let the world see how much of facebook fags they are by making it wall posts.
Fag 1: "Hey !! :)"
Fag 2: "Heyy Cutie <3"
Fag 1: "<3 I miss you :("
Fag 2: "I miss you too buddy :'( <3"
Smart Guy: "Wow you guys are facebook fags and nobody likes you"

One who posts mostly gay feminine material on their wall to hit on the new guy who is straight who the facebook fag has a boner for. Face book fags like dancing, playing with Domo, picking flowers, baking muffins, collecting gay porn, collecting vibrators, and looking at guys junk while using public restroom urinals.
I invited kevin to my friends list, we knew eachother from high school never really liked him but who cares its facebook. Now he's acting like a facebook fag on me posting very gay videos on his wall. He tells all his friends to call him gay as if he wants everyone to know hes available. I think he might have a gay little crush on me, looks like he's trying to proposition me. I'm going to just tell him that i'm flattered but I don't swing that way. He needs to know so that he can get me out of his perverted little mind.
