When a female is so amazingly sexy that you would adopt/put up with 2 of her illegitimate children and a bun in the oven just to get your dick wet!
Crosby: Hey man, check out that banging ass female over there!
Zack: Dude, she is fine. Would you "Brett It?"
Crosby: Hells yes!!! I would "Brett It" all day long! She gives me pre-cum just looking at her!!!
