Lub Dub Tee
"The first heart sound or "lub" results from closure of the tricuspid and mitral valves. It is a rather low-pitched and a relatively long sound which, as indicated in, represents the beginning of ventricular systole. The second heart sound, or "dub," marks the beginning of ventricular diastole. It is produced by closure of the aortic and pulmonary (pulmonic) semilunar vanes when the intraventricular pressure begins to fall. This "dub" sound is typically heard as a sharp snap because the semilunar valves tend to close much more rapidly than the AV valves. Because diastole occupies more time than systole, a brief pause occurs after the second heart sound when the heart is beating at a normal rate. Therefore, the pattern that one hears is one of: "lub-dub" pause, "lub-dub" pause, and so on. Sometimes, especially in young normal individuals, a third heart sound can be heard. This sound is produced by the very rapid influx of blood into the partially filled ventricle. It is typically very faint and as such difficult to hear" Reference: http://www.jdaross.cwc.net/normal_heart_sounds.htm

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
Smooth transaction and nice product, shipping was quick!

gooderesting the gooderesting thing ever made
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.
mine says "ass" on it lol
Good Decent, comfortable by all means
My wife bought this for me, my only thing about the shirt, is the big Vernon on the front. I think I would prefer it situated and smaller type as if overva pocket. Other than that I love it. Seems to be of good quality and easy wearability, but I have only tried it on, so am uncertain. Thank you for making my day
shirt made me cum
