When a person cannot perform a proper greeting - handshake, high-five, etc.

Can also be applicable to verbal greetings as well.
Physical - "Man, Cletus always crushes my hand when he shakes it, I think he has a greeting disorder."

Verbal - "Steve always calls everyone a D-Bag when he meets them. That jerk has a real greeting disorder."
