Get a male lactation mug for your grandma Jovana.
The white, warm liquidy substance that is projected out of a female cow's udders when tenatively massaged (much like ejaculate). Many think cow lactation is healthy when drank for life, but really causes obesety and foul smelling odors. This is the most horrific way to describe milk.

What's even worse than the image cow lactation brings to one's mind is the image of thousands of different cow's lactation mixing and rubbing together in a "milk supply" truck.. FUCKING SICK.
