A portmanteau ( I hope I spelled it right) of Mexican and nerd. The merd in question is not necessarily Mexican or Mexican-American, but because ignorant people like to call Latinos Mexican, then, any Latino who:

-Hangs only with other Merds or with the (Asian) Nerds (A MUST)
-May or may not have Yellow fever
-Doesn't listen to Rancheras, Durangese, or any other typical Latin music
-Cannot get girls (or at least not Latinas...yuumm)
-Socially inept (Optional)
-Knows too much about computers (some IT- guys can still get laid ie Bill Gates)

is considered a Merd. This definition is brought to you by a son of a bitch who decided to make this word up.
Diego is Merdy. He can't dance, thinks a girl is hot just because she's Japanese, hangs out with Chinese nerds, doesn't party and thinks Rancheras suck.
