A heterosexual who is flaming, that is to say acting more homosexual then the normal metrosexual. Flamosexual is considered by many to be an insult worse then the normal metrosexual. Flamosexuals are notorious for riding around in Ford mustangs.
Man, Alejandro spends so much time on his hair and puts so much gel that I swear he is a flamosexual...at least his mustang is cool.
a man who pretends to be gay in order to get closer to hot women. a faux homosexual.
"i finally did it with Crissy at Tony's party"
"no way dude. you are the greatest faumosexual ever! who thought two weeks of shopping and gossiping would really pay off"
"i know! and when she asked if we "did" anything i told her yeah we were both drunk...oh but it was ICKY"
a way of calling someone gay to a greater extent. if a person is so heterounusual that "faggot" or "homosexual" cannot describe the person to the extent of their gayness.
