The Urban Dictionary Mug
Sus cup I bought the sus mug for the sus king Daequan
Good quality, packaging shipped well, arrived quickly.
My mug came in broken but Urban Dictionary replaced it at no extra charge!
Excellent mug excellent service
this is the best for coffee and hot coco especially if you make the hot coco in it then pour it on your significant other and do body shots 😋🥱
I can pass away peacefully. This mug is everything I’ve ever needed and more. Fat thank you, Urban Dictionary. <3
I was really excited to receive this mug and when it did come it was perfect quality. My only complaint is that the color I choose was green teal but it came in yellow.
As always, easy to order and not-too-long of a wait for the finished product to arrive. It’s well-printed, and very sturdy. A great gag present for wedding party members.
The mug , color and saying are perfect! PMEO is what I say at work everyday. It has become a favorite saying for my coworkers when things go haywire!
Quality and style are outstanding relative to price point.
Love it! It is my favorite mug. Easy to hold because of its shape and weight. Now my go-to mug.
My wife is truly beautiful and this cup was perfect for her.
Awesome mugs! My GF laughed her ass off, lol!!!
t-this mug changed my life. At first i was a loner but then i bought this mug and i became HIM. I thank this mug everyday for its blessings
Cute, good quality, *****!
Exactly as expected!
My order was delivered very quickly and was high quality. Glad to add it to my mug shelf.
God is still alive. The existence of this mug shows there is still faith that god is dead and is listening to us. God Bless,
Gay Label Adore this. Ordered for my husband, with the second definition on the back, about the gay filmmaker. Makes a nice discussion starter.
Top notch shipping and exactly what I hoped!!
