A man called Bill who loves philladelphia cheese and eats it all the time, in hefty portions.
Gee-wiz, if I didn't know any better Bill I'd be calling that stuff Billadelphia with the amount you stuff down that pie hole of yours

A name given to a kind, warm hearted, gentle person who loves his Eagles-Phillies-Flyers but yet, in a wink of an eye, will rip off your head and shit down your throat when his team loses to any New York team. The nickname is extended by his neighboring New Yorkers who work/live among "Bill" in New York. These same New Yorkers have lost many a close family member who were once a Met, a Giant, and/or a Ranger fan by the above-mentioned beheading and following messy excretion.
Billadelphias drive their cars with an "Eagles" bumper stickers while stuck in Long Island traffic near their N.Y. home.
