Get the A willy schwilly milly gillymug. A middle aged midwestern male who fancies plaid shorts and cargos. Has an unhealthy obsession with BBC. Often found breaking laws while drinking Claws. Has as much taste in music selection as he does is fashion. Is unable to drive a vehicle with a sunroof. Considers himself "almost a doctor" but far from ever being a doctor.

Get the Gilliesmug. Can be quite a kind guy but can also be a dick. Gilli is ashy 9/10 of the times you see him so make sure you offer him some body lotion when you have some.

Get the Gilliemug. A Gillie is a Tweaker, a mooch, a fiend, will rob their grandmother to get their drugs, searching for the drugs in the middle of the day dancing to themselves on the side of the road scratching their face and ass continuously when there's nothing there picking themselves all over there body (corpse) treakers that look like walking dead 🤣🤣🤣🤣
