The term "surething" means exactly the same thing as the sentence or statement "Sure thing." This term is basically and almost always utilized in online conversations. It expresses a response similar to: "Of course" or "Hells yeah". It's used by hipsters and gangstarrs alike and also shows rebellion in the refusal to type another space (as if teens today didn't abbreviate enough). Part of the hipness of such a term is that it never has been and never shall be abbreviated. Ever.

S*********9 (9:47:23 PM): "Are you gonna make it to Eric's party tonight?"
c**************n (9:47:02 PM):"Surething"
