road rash

When you're overweight enough to have your thighs scrape against each other when you walk or run, and after a long day of walking or running, you get a horrible red rash on your thighs that you have to nourish for at least a day.

I was running on the treadmill for an hour, and when I got off, I had the worst road rash
