(Kiss Our Collective Asses)
You are all welcome to join. There is something quite satisfying in telling someone (if only virtually) to K.O.C.A. rather than simply "Kiss my ass." It feels like more of a team effort.
So, anyone who has a problem with us today may K.O.C.A. and, as my aunt would no doubt add: "Pack a lunch because it's going to take you a while."
