2. I saw Muamar Gadhafi at a NASCAR competition, wearing a Charlie Daniels Band T-shirt and a pair of cutoffs. I was so shocked, it was like seeing a souped up short bus.

1. A short bus that has been souped up, with engine modifications, chrome, spoiler, sidepipes, etc. In extreme cases, a short bus can be outfitted with the sort of suspension and oversize wheels seen on a monster truck, then entered in competitions. A very unusual sight.
