a mythological female that can be found late at night roaming around xbox live. she's sexy and she'll pwn you causing major damage to your male ego but it's all good because playing with smashleyy is a privilege. but don't get too attached for she'll vanish likehoudini, never to be played with again (unless you stalk her).
Dude, I was playing with that smashleyy chick and then she just disappeared from the server.
