n.

A person who gets little sleep during the week, and then attempts to make up for it by sleeping in and napping on the weekend.

"Spotted any Sleep Camels lately in your office? Sleep Camels are ultra-workaholics who go for days without resting, then power-sleep or power-nap for most of the weekend in an attempt to store up energy for the week ahead."
