shim 

when a girl looks so hideous or manly, or a man looks so womanly, you are afraid to determine what sex they are, so therefor you simply call them a "shim"

"jesus christ monkey balls did you see that shim tommy had sex with last night, i wonder who was even doing the fucking?"

"wow man, your new girlfriend is a total shim, i think i'll chase her with a torch and pitchfork"
