The Urban Dictionary Mug
Soaking is my favorite activity, glad I got a mug for it 😙
It DIDNT break :D
so happy you were able to put my unique word "Obergrossescheinehund" onto the new yellow mug. The yellow mug and black print make it easy for the words to be seen.
This is made by my friend i love it
Imagine not buying one of these. 🤢🗑🤡= non-buyer. Couldn't be me. 😎
It was the best thing I could have asked for
I mollywopped someone with it and it didn’t break. Nice
Product was as advertised and arrived pretty quickly too! The person loved their gift!
The "Pink Flamingo" colour with white text on a pink background is the best selection for this fine phrase mug. May I suggest you also correct the misspelling of "delightfully" in the default option for a timeless gift.
As always, a great gift.
It looks great. I couldn't have been happier
It’s a mug I would never find in a souvenir shop. I’m a legend in my own home.
I am very please with the mug. Thank you!

Was very happy with the customer service team when I had a question. They responded to my email quickly. The mug looks really cool, makes me laugh every time I use it and high quality. I’m in love with it. Thanks!
Haylee My name is haylee sullivan and the mug is describes everything about me and i would rate it at a 5 100% it is awesome
I’m right handed and would’ve liked it better if the handle was on right side with name facing forward instead of having verbiage facing front
girlfriend loved it :) - Ian's Girlfriend
