I do not understand the thread title.
Is is: "Boarders, no shit" as in borders, no duh kinda thing?
or maybe borders know shit, but that would contradict the thread.
My last possibility is that it is a shortened version of borders don't know shit. Maybe you condensed the don't and know into just no.
