The Urban Dictionary Mug
If you buy these mugs. You are a giga chad
They managed to squeeze the (edited down) definition onto the side of the mug in its entirety, so no complaints! Was worried it was going to cut off in the middle of a word or something.
The definition really makes it
Very prompt order fulfillment, and all the messaging was perfect!! Looks great! Thank you!
THIS MUG IS AMAZING!!
Love my mug! Everything looks perfect.
Just wonderful thanks
I am so thrilled that I found a mug with the exact sentiments I was looking for. This will be great in the future for birthday and xmas gifts.
I Like This Mug because im thicc and therefor this mug is thicc
Ok These mugs are really easy presents for the people you love i would find the best example of them and then buy and mug and give it to them as a present So simple
This mug is perfect! High quality product
My Aiden mug is awesome
This item was ordered as a gift, so you can imagine how happy I was to see it arrive in a box. Not only was it true to order in color and wording but was also without holes and held a strong cup of tea. However, I would not recommend green tea for this mug, or any mug for that matter as I prefer black teas. Emiyah will love it once she decides to return from France bringing her awesome hair and her kind heart and maybe some macaroons. I will put it to use until then and think of her fondly.
One word Respect ✊
I want to buy all the random word mugs in the world from you all 🙏🏻
Perfect way to start my day!
Ok it’s a mug drink from it act edgy with it who cares
This was a gift for my wife. She loves it.
The custom word and design came out perfectly, and my girlfriend absolutely adored the mug; I'll absolutely consider more custom-printed cups for birthdays and other occasions in the future.
Purchased this custom mug for my teenager, and they love it! The first comment was that the coffee stayed hot longer. Solid mug and the custom text isn't wearing ff after so many uses. Will definitely buy again.
