There's a difference in pronunciation between "minge" [minj] and "ming" as in "minging" though.
When I joined the army we had two lads from different parts of the country (Crewe and Newport). One looking at a picture of a bare naked lady in a magazine, one pointed out a certain part of her anatomy and declared: "look at the m**** on her!". The other chap asked what a "m****" was and when it was indicated he replied: "Oh, you mean her Qu**?"
This is an example of regional words for the same item. The two chaps in question were thereafter nicknamed respectively: "M****" and "Qu**".
Thank you English language for adopting the use of asterisks to replace smutt!
