An individual whose gender is unclear to everyone else.
I'm not sure if that person is a she or a him, therefore they must be a shim.

1. a thin slip or wedge of metal, wood, etc., for driving into crevices, as between machine parts to compensate for wear, or beneath bedplates, large stones, etc., to level them.

2. A not-nice word for an androgynous looking person. See also: shemale.

3. A seattle based rock band.
1. You just loosen the mounting bolts and slip the shim between the axle and brake backing plate.

2. Wow, you know, I was about to call the person over there a shim, when I remembered that would be fucking mean of me.

3. The shim are my third favourite band.

Deceived by a man's appearance into thinking he is a she. To get shimmed or be shimmed is to check out what seems to be a hot chick but turns out to be some fuckin' dude. She is in fact a him; hence, to be shimmed. Transvestism is not necessary for shimming, which more often occurs in everyday situations with long-haired males, sometimes but not always driving in that Jag convertible up ahead in the next lane. To be shimmed is always painful, but is made most acute by grizzled facial hair and direct eye contact with the shim.
Dude, I got brutally shimmed driving in to work today. Saw this hot skinny jogger in gold spandex leggings but when I got around to the front it was a fuckin' sunbaked old man! Goddamnit!
