an idiot that freeloads in your basement and stinks. they don't pay any rent and just watch movies and play video games also having little social skills.
Bill is still a bally wally in the basement freeloading and stinking the place up. He's never going to end his virginity.
The dumb bally wally just stands around like a rock when we have people over.
