pilot fish
an individual that is an expert at getting something from those around him/her for free. Usually obtains free drinks, drugs, money, a free meal... Just as a pilot fish attaches itself to a shark for a free ride.
Sure I'll buy this round.
It's your turn now, how about if you buy this round?
I have no money, sorry
What are you? A pilot fish?
