Like saying you have "a hit on someone" if anyone would hurt them for you.
" Yo, see that bitch over there? She's my ex's new girlfriend. Let everyone know, I got coins on her."

Briefly, "the realization that each random passerby is living a life as vivid and complex as your own." Originally from the Dictionary of Obscure Sorrows, which has a lot more beautiful neologism definitions like this you might enjoy.
