cumster diving 

When a woman, usually desperate for a baby, takes a used condom out of a trash can and uses its contents to inseminate herself. (read: When one man's trash becomes a woman's treasure.)

1. My man caught me poking a hole in the condom the other night and is withholding sex from me for a while. Once I gain his trust back, I'm giving cumster diving a shot.

2. -Whoa, you have a baby? When did that happen?

- About 9 months after a night of cumster diving.
