Get the mong mug.
A shortened version of the Shakespearian insult 'fish monger' from Hamlet directed at Polonius. There is debate to what the original meaning was but it usually donates to the nature of the fishmongers of the time who were money grabbing, corrupt, stereotypically simple and of low moral fiber. So mong generally refers to a despicable and or stupid person.

(Disclaimer: this is not a stab at anybody associated with the fishing industry. it is just an interpretation of another mans writing and opinions)

Get the monging mug.
Short for mongrel. A term usually used to describe someone who goes off with your ex boyfriend the minute you split up. At the same time she is also a 0 rating on the stunning scale and can often look like a ugly dog or horse. The mong also tends to buzz off presents you bought the ex, unknown to her.
How did you break up?
Oh he went off with a mong.
A Mong?
