Office Feeder

A colleague, usually overweight, who brings in unhealthy, sugary food to the office for others to enjoy. Psychologists believe this is done because the gift of giving to others eases the person's guilt of eating in conflict with his or her own beliefs from a health standpoint.

Because DeShaun brought donuts into the office AGAIN, he is an office feeder.

DeShaun: in an email: "Donuts are at my desk"
Jimbo: "Yo man, I'm trying to lose weight. Why you gotta be an office feeder."
