a co-worker who eats any and all food that is brought into work. He rummages through people's offices when they are not there and help himself to any candy, gum, cookies, etc. The food parasite NEVER, EVER brings anything in to share with other people nor does he contribute any money towards the purchase of any food.
Rudy is such a food parasite. One morning he ate a pound of bacon by himself when breakfast was served at work leaving some people with nothing at all.
