Fire Crotch

So I am not exactly sure what this word means in the "hollywood circles", but I know what it means in our house.
Take an average ordinary pair of jeans....

I wear them for a while and this happens.....

I tell you my thighs have mystical powers. I am able to set fire to any kind of clothes, not just jeans. Smokey the Bear, you should be very very afraid. I could be proud of this if I had super powers and was walking or running at lightning speed, causing my pants to catch fire, but please most of you know I can barely limp along. I may need to invest in some flame retardant clothing, or be known as fire crotch forever!
