Flat Spotting The Tyres

After a feed of pints, preferably stout, after letting a fart, a shart ensues. Nipping it in the bud leaves a little residue in the boxers, akin to someone revving and spinning a car wheel and leaving a small streak in the tarmacaden.

Jesus I was in bad shape last night. Had a feed of Guinness and ended up flat spotting the tyres during a presentation at work.
