One's legs as a mode of transportation. A play on the car brand Chevrolet. My car's in the shop, so I guess I'll have to rely on the ol' chevrolegs for a few days.
chevrolegs
n. the human legs, as used for transportation, instead of a car. (From the trade name, Chevrolet.) I’ll be late, because I only have my chevrolegs to get there—unless you want to give me a ride.
