Backfanny 

The backfanny is the slot that forms in the middle of an overweight person's back when they wear clothes that are too tight for them. It is called this because it resembles the vagina , which is also known in the UK as a " fanny " .

My Auntie Nellie is sixty five so naturally she's carrying a few pounds more than she did in her prime . How do I tell her that she sports a backfanny when she squeezes herself into that little yellow Summer dress ?

Barefanny 

Barefanny is the slang term of the name Bethany

It has two possible meanings

Barefanny: Meaning a fanny with no pubic hair to been seen

Or

Bearfanny: Meaning to possess a fanny that belongs to a bear

This stroke of genious was thought up by Tim in room 14 in his English class, whilst trying to get the attention of his fellow pupil Bethany- the name has stuck ever since and will follow her to her grave.

Tim: Oi Barefanny whats brewing!?

Beth: Bare...what?

(Everyone points and laughs)

Beth: Why are you laughing?!
