Yeast Mama
a girl with a busted used up yeast infected pussy who gets pregnant and has a loose vagina by the

age of 20.
Is very insecure about this condition so she hates on girls who have hot pussies and keep the guys coming back for more.

All that yeast mama achieved in life was 5 bastard children she couldn’t raise, a yeast infected unwanted pussy and no high school education.
