Packing a fat lip
When you stuff your lips so full of dip they look like they're gonna burst and leave a trail of goo everywhere.
My cousin packed a fat lip so hard he looked like a chia pet with a mouth.
That guy at the gas station had a fat lip so big it looked like he swallowed a can of dip.
My dog tried to pack a fat lip and now he’s drooling like a madman.
