Sunday Rest: belfie. Word Not To Use Today.

 A belfie is a photographic self-portrait featuring the buttocks.

The worst thing about this word is that it might give people ideas - and, sadly, they're all going to be really really bad ones.

Sunday Rest: belfie. The b is for bottom or buttocks or bum, and the rest rhymes with selfie, which is a shortened form of self-portrait. 

The Old English form of self is seolf.

I don't know why this comes up as the first image on a Wikimedia Commons image search, but it was a considerable relief.
