Similar to the phrase "kill two birds with one stone" this term means to complete two discrete tasks with a single action. The term traces its origins to a practice, originally made popular by aspiring major league baseball players on the Gulf coast of Florida, of hurling apples at the apparently limitless number of pesky seagulls.
As Mariah's girlfriend walked in on him banging her mother, Mariah thought to himself, "I've just killed two birds with one apple"; I've both fulfilled my MILF fantasy and ended this shitty relationship.
