It is the shortened word for Tissue. It is coined by the Dolan Twins three and a half years and a couple of days. It is also the days when the Twins coined the term "pap-towel" which is a shortcut for "paper towels".
Gimme a tish!
I said a tissue! You got me a pap-towel!

Do you know the difference between a tish and a pap-towel?

one of the results of MTV's newest censoring method: reversing all "unsuitable" words within a music video's audio track. well, at least it doesn't interrupt the music as much as inserting silence does.

Basicly the definition of a jerk with a large dick. None of the girls want to date him because he's such a jerk to them. Doesn't care about doing anything productive, ever. Honestly, if you ever meet a Tishe, I suggest you stay away. Don't let the big dick suck you in.
Ugg... that Tishe just walked by. He's got dat big dick though...
