referring to miss winchy, when you see a hoe and say "call miss winchy" your basically saying there a hoe on the loose and that miss winchy needs to bring them back to her whore house.
It is when you make a call to someone, then immediately hang-up to alert them that you are waiting for them to call you back, or, you do it when you are outside their door and ready to pick them up.
Hey George, when you reach outside my door, just misscall (verb) me and I will come straight out and meet you.
