Conversation jacker 

The nause that listens to a conversation and tries to take it over, unaware that they were at no point invited into the conversation so no one gives a fuck what they say.

Mike: so Steve who do you think will win the league this year?

Gareth: I reckon United have a shot

Mike: no one asked you Gareth shut the fuck up

Steve: yeah fuck off you conversation jacker
