The Urban Dictionary Mug
Great mug got one for my highschool crush
I was very pleased with the mug and I was thrilled that I could purchase a customized item that perfectly suited the person I was gifting. The only issue I had was that it didn't have the quote from the tv show the word came from as that was pictured on the mug prior to purchase.
Came out just as described! Had the full definition. Very pleased!
Perfect gift As a joke I gave one to my mate but I costumised it. It said tom drunk 24/7 ugly and got lovely hair. The lovely hair part was a joke coz he don’t have any. It was his favourite gift he got for his birthday and he drinks his beer out of it 😂
Great mug…. Got one for Cole M.’s girlfriend.
I ordered a customized mug for my gf and everything came out well. There were no autocorrect mistakes and the mug was unscratched. Would shop here again
Also got one for Cole M.'s girlfriend, even faster sex.
Istgd imma force my mum to buy this idek hw i find out but this shit looks fucking fire

Perfect coffee cup for a hockey fan. Great conversation starter.
Perfect gift! My husband loved it. So funny and clever!
Great mug… got one for my girlfriend… instant sex
As always, these are well made mugs that stand up to most anything. And they make perfect gifts (in this case for dirty-minded members of a wedding party). I’m extremely pleased.
Is a great mug that I purchased as a gag gift for a coworker. You know the one who also as interesting words/phrases that only urban dictionary can explain. Great as a coffee mug and better as conversation piece!
👍

The mug exceeded my expectations. Really excellent quality and build
Jim, you’re a fucking idiot interfering with accurate ratings and legitimate feedback. Get a hobby.
Great gift!
A little spendy, but worth it.
My wife kept talking about "ways out" being a Denver version of "psych" and she was right, so I got her this once I found it on UD. She loved it!
It's a great mug, will reccomend to family members my grandma gave me this mug for christmas and it was by far the best gift i got.
