Yump
Yump (scientific name of "yumperium") is the world's most superior mineral ever known of. every millennium it will plant itself inside several almighty "Yump Masters," who, once this happens, are legally the most superior sentient beings in thy universe. You may ask why - if this is a mineral, it hasn't been used or seen in everyday life, and the short answer is this: Yumperium is too superior for any pesky human to wield, and, the only other superior beings to survive close contact with this mineral without being chosen are the "Yumpers," who are physically gods of Yump, and are the creators of the mineral. Following the creation of the Yump mineral, (a mere 50 seconds after the Universe's creation) old Timmy, the good of Chinook Helicopters, attempted to steal the holy Yumperium, but was consumed by the mineral's sheer epicness. Timmy was flung far, far out into the void of interdimensional space and time, and, now only his evil children Chinook Helicopters live on... Another fun fact: The famous Orion constellation is actually a godly artist's depiction on what a humanoid form of Timmy must have looked like, murdering all those innocent Yumperium creators, in his haste to steal thy almighty Yumperium P.S: The Yump Masters have sworn to destroy and abuse all Chinooks remaining today, but, with more and more of them being manufactured by the evil factories, no one knows for sure who will win...

AMAZING I GOT THE HILAARIOUS SHIRT AND LOVE IT MORE THAN ANYTHING!

Feels great love the shitt
Great shirt. Great service. Shopify doesn’t track the shipment accurately though. However, when I reached out to Urban Dictionary customer service, they were able to help me.
Wore it to school.
Love this shirt so much

I love this t-shirt that says morbussy. It allows me to show off both my love for Morbius and the fact that I get no Morbussy.
This shirt feels great, perfect fit too.
Great looking t-shirt. Good quality. Printing looks good.
Cool I didn’t order anything I just have a lot of free time and not a lot of hobbies
Fun and soft.
Good stuff! Although, I do have a sneaking suspicion that this is cursed. You see, whenever i dawn this top-teir, soft, stylish shirt - I proceed to pass out within 46 seconds. The mere act of making contact with the material insues the process of this countdown starting. If I do not quit contact, i will lose conciousness the exact moment the countown hits 0. And when I regain clarity, I find myself in a bathtub - never mine, but a bathtub nevertheless. In the bathtub, there is always various colours of hairdye. I then have to go back home, shirt stained with dye. Very fashionable though! 10/10
