So after using "ish" in my own semi-ironic way for about the past decade...(ish :P)
as you my good friends well know to the point of nauseum.. (for example; "that band last night was rad!... ish" which obviously means they pretty much sucked. or "she's hot... ish". which means..she's alright looking. etc...) it's finally become apart of our lexicon;

here's an example someone sent me of it in urban dictionary
http://www.urbandictionary.com/define.php?term=ish

and check this out you can buy ISH t-shirts online!! check 'em out from American Angst clothes www.cafepress.com/americanangst.233648823 (Note their quote; "ISH" is the new "IT" word. My son says it all the time and it means, roughly, "Sort of but not really" but in a humorous sense. As in "Did you like my spinach pie?" He smirks and says "...Ish.") .
no fucking way right?!

i should be making that money shit, yo!

oh well, you snooze you loose...

i'm just glad to be apart of the every evolving english language.... ish

(they still haven't taken the fancy version of ish yet though.... ESQUE. that's for the true classy trashies ;) )

ish!
