The Urban Dictionary Mug
so cool! u can make sarcastic stuff too. i put: sarcasm: being an absolute asshole
Like the mug for my daughter, but didn’t notice that I had color choices when checking out. The yellow was pre-set so I got that color. Would much rather have selected a different color.
Cute, well-made mug! Exactly like the photo. I can't wait to give this as a gift this Christmas!
The description of a person by their names is the realest I’ve ever come across
Mug looks great and everything is spelled correctly.
I love my mug! 💘
the photo is all you need to know.
It’s pretty damn cool
It was a really good hoe mug!!!!!
Exactly what I was hoping for! Great product
My coworkers see all the cups I order from you, and this one is already one of their faves
Just what I expected. Merchandise looked just like it did online. Showed my friends and even they loved the cup! Plan on ordering more merchandise from you guys. Thanks. KLDS
Astounding Mug. I found this Mug in a dark time, the time when I needed a mug the most. I went onto google.net and found this truly amazing piece of craftsmanship. Manny Heffley came out of my computer and started to gyrate, before hopping out completely and eating my asshole. It felts so good, I started shaking and moaning, rapidly convulsing on the floor. Manny Heffley slowly crawled into my, hiding in my womb in order to store his power for 12 months and evolve to the form of "Baby 2". Thank you, Urban Dictionary. This mug changed my life.
Looks great and quick delivery
very good quality, wasn’t broken or anything and was a good gag gift !
I gave it to her today. And she loved it said it was her to the T
The Printing wasn't very sharp, but it's good enough.
It was a surprise gift for someone and she absolutely loved it!
This was sent as a gift to my grandson, who lives in another state, so I never saw it. However I asked him as follows: "Just checking ... their request for a review shows an aquamarine mug ... it was supposed to be purple (eggplant, they called it). Was it purple?" Then he said: "It was purple! And thank you I love it haha Sent from my iPhone"
Shipment arrived quickly and in great condition. I know my custom mug will be a crowd pleaser when my girlfriend opens it up for Xmas.
