The act of sexually arousing a female. As her vagina becomes wet, her basement floods.
Guy: "I'm flooding the basement right now."

Girl: "You sure are, now fuck me!"

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.
