This might almost need to be in Creative Expression. Running from A to Z, we need Euphemisms that start with each letter of the alphabet. But.... each euphemism must fall into the
one-word category pre-selected by the previous poster. They don't have to be well known, in fact you can just make 'em up

Or you can be cliche. For those that like an extra challenge, why not make the category you set start with the same letter as your answer? It's not cricket to set an "impossible" category, but this is the cellar, so if you must be a spoilsport....... we'll be sure to rise to the occasion (or sink to it...).
Example:
Dwellar1: A sandwich short of a picnic. Next Category: GONADS
Dwellar2: Bollocks. Next Category: PETS
Dwellar3: Can-Opener Detectives. Next Category: CHILDREN
aside....
Here's an interesting page I found whilst looking for new and creative euphemisms.......

OK, I'll start
