look up any word, like cunt:
To claim credit for a now-common word or phrase usage that either clearly belongs to the public domain and only recently became popular by random group adoption and proliferation, or that was actually brought into vogue by someone else. This usually occurs when the word/phrase's acceptance happened too long ago for anybody to have a clear enough memory of its adoption to refute the claim of invention/primary adoption. Also, one who makes such erroneous claims.
Friend 1: "I feel like I pretty much invented the phrase 'I feel like'"
Friend 2: "You can't "invent" 'I feel like.' Way to Snides that shit.
Friend 1: "Nah. I also started "I mean."
Friend 2: "Shut the fuck up, Snides."

a person who lives in tracksuits constantly, often with a pair of rockports on their feet and a burberry cap. can be found listening to 'banging choooons' in their Nova's or Astras. If they are not there try a council estate as they may be there impregnating their under age also snidey girlfriend (noticable by badly dyed hair piled on top of head and wearing jeans, rockports and some form of sport coat. May also be already pushing a pram).
oh my god you look well snidey
