When someone creates an easy opportunity for you to flirt, either with them or someone else.
This example was in response to a boy telling a girl to switch her display language to "Pirate" in Facebook:
The ball is passed from the girl:
"Ok I am going to try to be a pirate. I am excited, does this mean that I might get some booty??"
the Flirt Layup:
"booty? You don'ts needs whats you already gots! ar-ar-ar!"
