Wall Huggers 

A play on the term 'Tree Huggers'.

On facebook, where two or more people (friends) fill the need to self-consciously have conversations on each others walls so the whole world can see. Its usually in the form of in/personal jokes, banter, boasting or organising an event/outing/social gathering

Guy: Why the hell does Tristian and Hamish feel the need to clog up my news feed with this random conversation that no one wants to see or read! Why can't they use chat or message each other?

Guy 2: They are Wall Huggers.
