Blechty?

[Rebecca111]

i dont know how you would spell it but is 'blechty' a slang word meaning not nice or disgusting?

[Quizmonster]

It sounds as if it might be a dialect - Scottish, perhaps? - version of 'blighty'. That word is also, of course, an old soldier's word for England, but in this case it means 'affected by blight'. And that means it withers or spoils whatever it touches...ie might make it disgusting.

Or might it be a newly-coined onomatopoeic word related to the expression 'Blecchh', indicating nausea?

Where are you from Rebecca? I strongly suspect South Cheshire.

The word "Bletch' is very localised slang for filthy grease from Crewe Railway Works!

Apparently, steam locomotives from Bletchley engine sheds were brought regularly to Crewe for repair and servicing, and those from Bletchley were always very much dirtier than those from elsewhere.

Bletch as a synomyn for filthy, greasy muck passed into local general use - to this day people who've got dirty will say, "Look at me, all covered in bletch!".

I'm really curious now, please tell me where you heard it!
