Mong

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.
