The Urban Dictionary Mug
Well printed, the mug's ceramic is of good quality, I'm not sure what else I can add. I am surprised it could be printed and shipped so quickly based on my earlier experience printing/kiln-firing/baking this kind of product. Well done.
Sent to a friend. He loved it!
I can't stop putting weird things on the cup I love this website 😆
Purchased this for my fiancé. One night watching TV, she blurted out the word "kaputnik." We laughed so hard. Never dreamed it was an actual word. Now, we know better. LOL
Sent a mug with DABNABIT printed on it to my Grandaughter for her birthday! She absolutely was thrilled with it! This is a saying I’ve used over the years a lot & we’ve always laughed about it! Ordered myself one too!!
Best mug I've ever seen honestly
looks great, came quickly, exactly as I wanted. minor observation - the coffee mug was a bit smaller than I expected. The mug is normal size, but most of my mugs tend to be a bit larger. No matter. I still enjoy it!! Perfect would have been larger - but that I my preference.
Bought this mug as a joke, the concept of there being a "magical one" was very funny to me. Great quality, I even feel magical myself.
Perfect!!
My nut hurts my nut hurts help
i bought this mug for my classmate and he likes it since its his crush name
Great mugs, great format, always fun to buy for friends!
Weird text for a dad mug Why can i put Infantile Pillock on a mug for my dad? Pretty funny
my partner thought it was very silly
Funny cup that my girl absolutely loved!
Arrived safely and in one piece. New term is already being used in the office loosely.
Got it for my friend when he was mad. Very funny
Always wanted a communist coffee cup. Great price too.
I’m excited to have gotten it. I’m going to give it to a man at my church that volunteers this time and won’t stop working! So the inscription is perfect for him.
Why?! I can't stop doing lewd things to this mug, it keeps on telling me to stop but I respond with hitting it. PLEASE HELP ME! 😭😭
