Gaemo: A closeted gay man who has a propensity for talking about all the chicks he is banging. This person is also bitter and depressing.
The spelling comes from a combination of the words gay & emo. This spelling looks more Gothic or Ren Faire and fits with the "emo" theme.
I wish Alexander would stop being so gaemo. He shouldn't talk about all the chicks he wants to fuck while sipping a buttery nipple at an establishment like The Man-Hole. And Alexander, enough with the skinny jeans & guyliner you depressing douche bag.
