Sexy in the form of Shrek. Originated from online memes including "Shrek is love, Shrek is life."
Widely used by hardcoreShrek fans to describe something great or nice looking.
John: "Check out this picture of J-Lo from 2009"
Greg: "Shmexy"
Used to describe someone who's sexy, but in a wierd way. It's very rare to find someone who everyone will agree is shmexy, as it all comes down to personal taste in the end.
Guy 1: "eeew look at the state of her! She looks like Jay Leno and a pig had a kid!"
Guy 2: "hey, she isn't that bad. In fact, I think she's pretty hot.She's kinda shmexy, yano?"
Guy 1: "now you mention it, she is....in a shmexy kind of way...."
cool. thats seriously ALL it means. just cool. it has nothing to do with the word sexy, or smart, or smart and sexy, which some people have guessed it means, but no. just cool.
Note: Back in 5th grade, me and my friend alexis made this word up, and therefore have the right to make it mean cool.
Note: in some cases it can mean sexy, but only as a joke, like when talking about an ugly person: "Wow, he's super shmexy". but it is never a synonym for the actual word sexy, since it does not mean hot, or hott, or 'bangin', or anything else like that
