look up any word, like cunt:
 
1.
Sny
Bay Area slang describing one who is exclusive, two faced, talks shit, wretched, and ungrateful. This word is never used in a good manner. No one likes someone who is sny. Also used to describe something that gives off bad vibes. Do not confuse this with sly.
Wow that bitch is sny.

Don't be a sny hoe.

That's hella sny.
