Which word means a polite alternative to an unpleasant term?

Deborah , I like “I need to see a man about a mule” also. LOL

A few sandwiches short of a picnic?

My late mother in law used euphemisms like, her daughter couldn't consumate a marriage, birthday suit, etc.

For me, all this talk about euphemisms is just a load of euphemism.

The euphemisms for toilet is washroom, restroom or the facilities. A euphemism for human defecation could be, " I need to see a man about a dog."

I've heard about this euphemism. but I suddenly forgotten 😞
