Dump Stat 
This is based on Lestor, a character in my Pathfinder group. Alas, he thinks that he is a people person, but often ends up causing more harm in his attempts at diplomacy than good.
Seriously, some (otherwise friendly) princess challenged him to a duel because he failed at diplomacy so badly.
That being said, having a low Charisma score can lead to some pretty hilarious role playing, and Lestor’s player does a pretty good job at it.
