A Eugenoid is a growth that forms on the ball sack. It can be a variety of colors. The worst kind of color to have would be green, meaning infection with round worms inside of the eugenoid.
"Wesley Johnson has a Eugenoid that is pussy and uncomfortable. His ball sack growth is pink, this means that he has an accumulation of blood and ticks in his ball sack growth."

"Maurice Williams has a nasty rotten Eugenoid that is green. Maurice has round worms in his ball sack growth. Maurice caught his Eugenoid from a women , named Fiona, that has a sloppy taint."

"Bria doesn't have a Eugenoid because she is a beautiful, pristine, and drop dead gorgeous kind of a girl."
