A person that generally gets used on a regular basis, or is an overall mark. This person also packs fudge very often. This can also just be an insult for whatever you like. And last but not least the person your saying to it may actually look like a Big Toe on a Foot.
"Dude, why is Jake such a Foot?" "Because he is a frickin' fudgepacker mark."
"Wow why did you say I was late to class? Stop being a foot."
