hungry hippo
Another immature yet mildly amusing term created by the bashface crew.
Initially a nickname given to a younger crew member, the term has grown from strength to strength due to its increase in use.
The term describes a person who, either wants/needs/(is hungry for!) to take illegal substances, and due to this hunger,they become obsessed and attached to many aspects of the drug such as people,raves,staying over at peoples houses for extended lengths of time etc!
It is overall a joking, yet mildy undermeaning term.
"Good Evening (Hungry) Hippos, how are we all ?"

            Or 

"Who was that on the phone?"
"Oh it Was some hungry hippos!"
