It is your last pair of underwear before you know you have to do laundry. E stands for emergency. This is usually the pair of underwear that is your least favorite and gets very limited usage. It is the pair of underwear that has no rips or tares.
I knew I had to do my laundry when I had to wear my e-briefs.
