Flood the basement 

Made famous from the drag queen Ginger Minge on Ru Paul's Drag Race Season 7, flood the basement refers to moistening of the vagina prior to or during sexual intercourse. The joke here is that (as a woman in drag) she is so turned on by said person that instead of being moist, she flooded her pants with twat juice.

I look at Santino Rice and instantly flood the basement. vaginal fluid cunt juice cum clam juice lady smegma ginger minge

Flood the basement 

When you pee you pants while standing and it fills up your shoes.

Typically I wear Tevas when I pee my pants, but today I wore my Chucks and had to flood the basement.
