It's because in 120 degree weather you sweat all the fucking time and even a shower once a day won't cure the stench of sweat caking under your clothes and in your hair, filling your pores and soaking the sand that is already on your skin, as you either sit in one spot for hours or walk to your next destination, creating more sweat and filth until you stop and fill a bucket full of water to swirl your clothing around in, knowing that it will still smell like shit, just like the smell in your hair and on your skin, because you're living in a Godless hell hole. That, and wiping with only your left hand. Sick fuckers.
