A Gleep is the name for a person who basically doesn't want to do things the "easy" way. They are feisty and giving trouble. They
don't knuckle under pressure nor give in to paying a "protection" fee for either themselves or their business and go so far as to "spit in someone's eye" to show they won't be bullied by
gang members.
Because of this, they aren't
long for this world and are often killed by someone in that
gang, usually to leave a message to the other merchants, "pay or else ..."
Dialogue from Twilight Zone, "Nervous Man In A
Four Dollar Room."
"So tomorrow morning, they find the old gleep sprawled across his
bar. And then all the rest of them swing in
line."
