To pack a fat hog, meaning you packed a 3/4 of a tin of Grizzly or Copenhagen mint (long cut obviously). The size of your lip usually visible from 20 feet away, and only true dippers send it.
Yo dude, I packed a fathog yesterday and gutted it all!
A sibling or parent that just simply eats to much, even though they don't gain any weight. If you ever have a older brother that looks like a twig, let them know they are a fat chicken!!
You: Kyle, stop eating all the food!! You are such a fat chicken!!
Kyle: I am a twig, what are you talking about?!
