double chin deepthroater
When a person's neck and jawline is completely sagging from deepthroating a cock. Usually found on pedophiles as they carry too much weight promoting pedophilia, as nobody wants to have sex with an obese partner. Straight men usually get one. They obviously suck cock in secret (as their sagging jawline indicates).
Holy crap, that pedophile with a double chin deepthroater neck has the nerve to care about posture. How could posture be more important than weight.
