Cheggers

Cheggers(As in Keith Chegwin of Cheggers Plays Pop fame)- Meaning- preggers ie Pregnant.

Cheggers as pregnant in general or with Chegwin offspring in particular?

I think the word you intended was 'euphemism'. MWO: "the substitution of an agreeable or inoffensive expression for one that may offend or suggest something unpleasant." Or possibly 'euphonism'? Not in the dictionary, but it would mean 'pleasant-sounding'.

IMO a bit daft that one - Cheggers is a bloke and 'preggers' is widely understood and no greater word-length.

If you just want to be diffeent - why not say "gravid" - it's correct and that little bit different.

Is "enciente" an alternative?
