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 like houdini, 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.

Yo mang, smashleyy sounds super hott.

Smashleyy beasted our entire team last night in a death match.
