house troll

House troll- Roommate who loves to scavenge your food, drink your booze; make a mess and not clean up; then disappear into the room cave when there's work or help needed. They enjoy appearing and taking full advantage of parties and visits by the ladies... then once again... disappear after they scavenge the wine/ food/women that is not theirs; then scuttle back into the cave.

We just spent hours getting our party together and the house troll shows up again just in time to drink Jerry's wine and disappear out of sight again.
