Mug is an insult. Mainly an English term, so I'd appreciate it if my yank friends wouldnt vote a thumbs down just because you've never heard it before, awrite? Good, ya mug.

Its hard to give a precise definition, but basically a mug is a naive or easily cheated person, an idiot, or just somebody you dont like

If you use the Urban dictionary, there is no chance of forgetting the meaning of the cup. A big glass that the Urban sells by printing every word, even shit on it.
- What does it say on the mug?

- Ohhh it says shit.. I got it from Urban.
