An unintentional, seconds-long nap that you take most often in class or a really boring meeting. So short that usually nobody but you notices.
I caught myself taking a nano nap on that conference call.

A very short nap, lasting only a minute or so. Shorter than a cat nap, a nano nap is used to just focus your mind or recharge quickly. You can take a nano nap in nearly any position in any location.
Although nano naps are very refreshing, I don't recommend taking one in your car waiting on a red light.

When You Fall Asleep listening to your ipod nano.
I had a nano nap & missed my favourite song.
