WOMB is acronym, means; Waste Of Mega Bytes.
Dude, you haven't log'd in your myspace, you're such a WOMB.
A mixed word of 'Horny' and 'romantic'. People use to elaborate that word, perhaps; who are really desperate or a defense mechanism to keep them away from embarrassment.
<i>"At least, I'm hormantic like any other guy."</i>
