Simp (noun): A man that has forgotten the most basic rule of any negotiated relationship: Always be ready to walk away from an unfair deal.

Without the courage to walk away, one is, effectively, a dickless slave. Spiritually, such a man is equivalent to a eunuch, and will be consumed by passive-aggressive behavior and the endless pursuit of instant gratification as he subconsciously wrestles with his own self-inflicted powerlessness.

Truly the saddest form of man.
