Tetraëteris Tee
A tetraëteris is the Greek name for the period in 4 tropical years where the Moon phase occurs 2 weeks earlier, defined as 49 synodic months, 52.961595389901795 sidereal months, 53.174596199249 draconic months, 52.513969931831795 anomalistic months, and 1,446.998810185187 days. Though if you intercalate it, you get 50 synodic months, 54.04244427541 sidereal months, 54.25979204005 draconic months, 53.58568360390999 anomalistic months, and 1,476.52939814815 days. If you go halfway between 49 and 50 synodic months, you get 49 1/2 synodic months, which’s 53.5020198326559 sidereal months, 53.717194119649506 draconic months, 53.0498267678709 anomalistic months, and 1,461.7641041666686 days, which makes up half of an octaëteris, leading from a new/full moon to a full/new moon less than 1 day later. Which’s just about 4 full synodic revolutions of Uranus, and leads from a new/full moon to a full/new moon within 15 days later. The tetraëteris has been used for the Olympic games in that if the Olympic games of a games occurred 49 synodic months after the last events, then the next games would occur 50 synodic months later, then 49 more later, and then 50, vice versa, as 49 + 50 = 99 synodic months, making an octaëteris.

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

Got it for a friend! He loved it
Size was accurate, and printed text was as displayed online. Doesn't hurt that the material is pretty soft either.
