Get the Fat bum mug.
An absolute waste of space with no job,no aspirations, relies on everyone else and does fuck all with their life.

Generally a fat lazy twat.

Someone that would be happy to spend their life on benefits as opposed to doing a days work.

Get the Big Fat Bum Dosser mug.
These are the morbidly obese people on news reports standing in food lines waiting for free food. You can indentify big fat fucking bums in two ways.
1. They're usually claiming no job or food but have cell phones.
2. They're generally standing in line in front of the skinny people that really do need the food.
Hey Glenda, I saw you were in that line getting free food on the news last night. You're a dear dear friend but I must tell you that you're a big fat fucking bum for doing that.
