Homunculus
a tiny fully formed individual that (according to the discredited theory of preformation) is supposed to be present in the sperm cell Hippocrates and Aristotle proposed the idea of what they called pangenes, which they thought were tiny pieces of body parts. They thought that pangenes came together to make up the homunculus, a tiny pre-formed human that people thought grew into a baby. In the 1600s, the development of the microscope brought the discovery of eggs and sperm. Antonie van Leeuwenhoek, using a primitive microscope, thought he saw the homunculus curled up in a sperm cell. His followers believed that the homunculus was in the sperm, the father “planted his seed,” and the mother just incubated and nourished the homunculus so it grew into a baby. On the other hand, Regnier de Graaf and his followers thought that they saw the homunculus in the egg, and the presence of semen just somehow stimulated its growth. In the 1800s, a very novel, “radical” idea arose: both parents contribute to the new baby, but people (even Darwin, as he proposed his theory) still believed that these contributions were in the form of pangenes.
The Urban Dictionary Mug
Great mug got one for my highschool crush
I was very pleased with the mug and I was thrilled that I could purchase a customized item that perfectly suited the person I was gifting. The only issue I had was that it didn't have the quote from the tv show the word came from as that was pictured on the mug prior to purchase.
Came out just as described! Had the full definition. Very pleased!
Perfect gift As a joke I gave one to my mate but I costumised it. It said tom drunk 24/7 ugly and got lovely hair. The lovely hair part was a joke coz he don’t have any. It was his favourite gift he got for his birthday and he drinks his beer out of it 😂
Great mug…. Got one for Cole M.’s girlfriend.

Great mug… got one for my girlfriend… instant sex
As always, these are well made mugs that stand up to most anything. And they make perfect gifts (in this case for dirty-minded members of a wedding party). I’m extremely pleased.
Is a great mug that I purchased as a gag gift for a coworker. You know the one who also as interesting words/phrases that only urban dictionary can explain. Great as a coffee mug and better as conversation piece!

Jim, you’re a fucking idiot interfering with accurate ratings and legitimate feedback. Get a hobby.
