Longer than a power nap, shorter than a proper sleep.
Gosh I loved that nanna nap

A short lie-down in the afternoon. Beloved of grandmothers and anyone who doesn't have an exciting enough life to take a disco nap.
I was so tired this afternoon that I needed a nanna nap even though I don't have a big night out planned!
