Get the stiffinmug. A drunken motion of a dude in your group who’s self conscious about being around 5 foot 5 inches but it’s more because he walks around downtown with his boys in the same bumbling sloppy motion that their 5 inch dick wiggles in his power rangers underwear. These types of people are rumored to grow landing strips in their taint areas.
