e - meaning online
peen - short for
penis
A person's ego, pertaining exclusively to their online personality.
e.g. a big e-peen = a big online ego.
Unlike rl-peens (i.e. a real life
penis), e-peens are 'flexed', brandished, whipped around, (or otherwise used) with unfailing regularity.
Another difference between e-peens and rl-peens are that e-peens can shrink and grow exorbitantly, i.e. more than a regular
penis would with an erection.
