Bird of a Feather Flock Together 

Bird of a Feather Flock Together is a term used when describing a Group of people who always hang together, and or associate with one another. Even when they all may not share the same common interests, outside in public view they're all just viewed the same (a Feather on a Bird's back) just by Guilt of association.

"You know the old saying, you hang around 10 Fake individuals you're likely to be the 11th one. Bird of a Feather Flock Together. You're not just an associate of them, you're one of these fake individuals as well ."
