The Urban Dictionary Mug
FUCKING BEST CUP EVER NGL
The coffee mug looks great and always draws comments from those seeing the first time.
The coffee mug looks great and always draws comments from others.
perfect for when im expressing myself <3
So fun! Looks just like I expected. I like that I could edit the mug to say what I want.
The mug is beautiful and I love it! Thank you for having a handle large enough for a man to hold onto! ♥️
Istgd imma force my mum to buy this idek hw i find out but this shit looks fucking fire
Jim, you’re a fucking idiot interfering with accurate ratings and legitimate feedback. Get a hobby.
I gave it to my friend who took money from me and never returned.
Loved this mug! So unique and you can edit the text to add something unique.
It's simply awesome; and plus, the word means a lot.
okay so the mug was mid but when you have a genz meme and give it to one of the most serious people you know then it's pretty funny
The Printing wasn't very sharp, but it's good enough.
It DIDNT break :D
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.
This is to test if the Urban Dictionary store rating system is working and not showing fake 5 star reviews.
This mug is incredible! It was a great gift for my friend named Jacob, who is definitely gay. (Even though he says he isn't 🙄)
dear Jim. B whose 1 star test review is showing up on top: thank you for your service sir
These mugs are supercalifragilisticexpialidocious!
Hello, I am here to present if this is a real rating system or not. If you are reading this it's a true rating system. But if this doesn't make it, urban dictionary, I know what you are doing.
