Nameghanged for this. They are vile, boastful, cliquey, backstabbing oddballs. Can't go into too much detail or give examples unfortunately, much as I'd like to.
I can't really discuss them with DH (obviously) or others in RL so I'm venting here!
Have to pretend I like them for the sake of tact and equilibrium 
So, anyone else keeping their dislike well hidden?
