smooch hanger

A "Yes" man. A person who hangs around someone popular or perhaps influential status and is always kissing their ass.

Samantha is such a smooch hanger. She never stays at her desk or gets any of her work completed because she is always clinging on to Mr. Big.

Jack is making a fool of himself by blatantly sucking up to his rich neighbor. I am embarrassed for him because he is a silly smooch hanger!
