a condition that happens to certain males when they think about the waitress "Flo" from the t.v. show "Alice".
Dude, I was watching an old rerun of "Alice" the other nite and man when she says "kiss my grits!" my penis gets a bad case of the Flo Grow!

Its an STI in which the infected persons genital start to grow mushrooms. If left unchecked, this condition will lead to a "Blue Waffle"
