This Rude Fuck You Novelty Mug has to be the funniest, and possibly rudest, cool mug you will ever own.
The ideal gift for any moody person in your life that just doesn't want to be bothered or talked to, this fun mug will make people think twice before they ask you to do something again.
Have fun and make someone go away without having to actually say anything but make sure you hide it when the boss comes over, we can't be responsible if you get fired.
