I know all about that. Once gashed my forehead open from hairline to eyelid (right through the eyebrow), couldn't see from all the blood. I was a kid when I did that. Lesson : Always listen to grandpa when he tells you not to ride a scooter in his garage, especially around his mint low mileage bought new in 1971 Twister and a Boat... Guess which one I hit when the scooter kicked out from under me... yep, I head butted the boat motor :prayer:
This could go either way.. Either the shorts fell off, or you burned your leg on the exhaust. If your luck is anything like mine, it was probably the first one.
