The definition of Monastra is a male who is sneaky, shady, greasy grifter. A soulless creature that lurks and preys on powerless victims for their own gratification typically because they are sexually inadequate. They have highly addictive personalities and are prone metal illness. Never, never trust a male Monastra.

The female version of Monastra is the opposite. They are trustworthy, kind, compassionate and beautiful inside and out with unmatched passion for the peace and all that is light in the world.
"That guy is a narcissist. He's the worst type of conman, he's a total Monastra, so don't trust him."
"She is the girl of my dreams, a total Monastra babe! She will be my wife one day!"
