I just realized why Thresh is named as such

Look up Thresh on the dictionary. If you did not know this already prepare to get your mind blown.

EDIT: I just saw the notification about a post getting deleted because it had too little information (?). I'll put the definition right here: THRESH(v.): verb (used with object) 1. to separate the grain or seeds from (a cereal plant or the like) by some mechanical means, as by beating with a flail or by the action of a threshing machine. 2. to beat as if with a flail. verb (used without object) 3. to thresh wheat, grain, etc. 4. to deliver blows as if with a flail.

I think it's really funny how Flail also fits into his kit.
