Pariah (3.5e Flaw)
From D&D Wiki
You are suspicious and up to no good, probably...
Effect: All social creatures with an intelligence score above 5 have a +2 spot and listen check against you. You take a -2 penalty to all charisma skills made against them.
Roleplaying Ideas: It might look cool, but getting a full facial tattoo of a bleeding skull was a bad idea. And pull down your hood! The skies are clear; You look like a hoodlum covering your face like that.
