finders keepers
A phrase which, as well the well-established meaning of "I found it, it's mine", announces an impending mugging, much like a highwayman command to a coach party to stand and deliver.
Particularly loquacious bullies in the Wild West of Scotland might say "fin', keep: brek beak" which roughly translates to "I'm going to pat you down and if you've lied about not having anything, you get a fucking broken nose".
