It is the ability of extraordinary people with strange powers who are able to "blend" and "mesh" their abilities together. In this way, they are able to act as one organism. They progress toward a mature gestalt consciousness, called the homo gestalt, the next step in the human evolution.

It is based on a concept developed in a science fiction novel by Theodore Sturgeon titled "More Than Human" published in 1953.
"Blesh" is a portmanteau of "blend" and "mesh".

An acronym, taught at the seldom heard of 'Excel Basketball Camp 1997', that helps one shoot a basketball successfully.

B. Bend (Bend your knees)
L. Lift (Lift your legs)
E. Extend (Extend your arm)
S. Snap (Snap your wrist)
H. Hold (Hold..)
Your shot is poor and you don't make any shots. Perhaps you should practice your BLESH. 'Thanks Excel Basketball Camp 1997!'
