Dark Matter
1. Unprovable hypothesis that since galaxies and galactic clusters don't have enough mass to produce enough gravity to spin the way they do, that there thus must be invisible matter hiding that's making it all work. 2. The observation of the universe sometimes fails to follow the known laws of physics, so instead of theorizing that there must be more laws we've yet to discover, scientists have instead decided to push forward the idea that invisible masses must exist, and thus explain away the discrepancies and gaps in our knowledge. 3. Science akin to religion in that nothing at all proves it, but lots of people believe it because it explains something that was hitherto before difficult to understand. 4. Theory regarding matter and gravity that seems to make sense of Newtonian physics when it fails us, but in doing so introduces a concept that is completely ludicrous. 5. Alternative hypothesis to how the universe works to the much more logical MOND theory, or variations thereof. 6. An example of lazy science. 7. The greatest example of how extremely intelligent people can at times be completely clueless, lacking in all common sense.
The Urban Dictionary Mug
so happy you were able to put my unique word "Obergrossescheinehund" onto the new yellow mug. The yellow mug and black print make it easy for the words to be seen.
This is made by my friend i love it
Imagine not buying one of these. 🤢🗑🤡= non-buyer. Couldn't be me. 😎
It was the best thing I could have asked for
I mollywopped someone with it and it didn’t break. Nice

Product was as advertised and arrived pretty quickly too! The person loved their gift!
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.
As always, a great gift.
It looks great. I couldn't have been happier
It’s a mug I would never find in a souvenir shop. I’m a legend in my own home.
I am very please with the mug. Thank you!

Was very happy with the customer service team when I had a question. They responded to my email quickly. The mug looks really cool, makes me laugh every time I use it and high quality. I’m in love with it. Thanks!
Haylee My name is haylee sullivan and the mug is describes everything about me and i would rate it at a 5 100% it is awesome

I’m right handed and would’ve liked it better if the handle was on right side with name facing forward instead of having verbiage facing front
girlfriend loved it :) - Ian's Girlfriend
the urge to buy it and write cum on it
Purchased this mug as a Christmas gift. Can’t wait to see the reaction!
This is to test if the Urban Dictionary store rating system is working and not showing fake 5 star reviews.
These are hilarious! Great gifts. Cost seems a bit high but i couldn’t resist.
