Lub Dub Mug
"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

FUCK YEAAAAAAAA! MUUUUGZ WOOOOOO
Happy with my purchase
amazing I will buy this. it will be my child. I WILL BE KING OF THE 0w0
I loved this mug! when i drink out of it it always has a horrible stench and honestly i dont mind because i love smelling it. my boyfriend thinks i should throw it away because he says "its has lead poisoning" but i cant get rid of it. when my mom died i bought her a mug that said "deceased" because i thought it would brighten the moment when i open presents at her funeral (it worked). but if your looking for something to buy, you should really get one of these mugs. they are cute, nerdy, and remind me of my dead mother!
Yay. I got a mug... And it has the most accurate definition of my name ever lmfao. The quality is great and it's totally worth the price. For me, at least :)

this mug reminds me of my cat, it does nothing and cant pour me a nice cup of joe. It is horrible, it doesn't tell nor does it allow me sip on it. It stops me from drinking from it, its like the mug is trying to torture me.

Had no idea my name had a definition!!
Bought for an inside joke. Perfect.
