Toenail polish is part and parcel of any woman's make-up sack but guys typically come into contact with toenail polish only if they have a girlfriend and she wants to brand him without using irons that you stick in a fire.
I for one am grateful for toenail polish because I've heard that branding is quite painful. That and branding seems like it would be confusing as well. You see a guy with a Bar S or a Circle J branded on his shoulder and what exactly is that supposed to mean?
Boys don't paint their toenails . . . eh.
