Never heard this before, but now that I have, I’m going to be yelling this at ryeth any time she steps out of line. KYR stands for “Know Your Role” and was recently related to ryeth as part of a story from a co-worker. Evidently, the story went like this. Ryeth’s co-worker is sitting down watching TV with her new possible boy friend (the co-worker is recently separated and is now dating for the first time in a long time). The boy friend asks if she would mind making him a sandwich. Not too horribly out of line if he’s at her house for only the second or third time and doesn’t know where anything is IMO, but certainly I would have just asked where stuff was and made my own. In any case, she agrees to make him one, and while in the kitchen she hears him say “KYR”. She doesn’t know what he means, and he said, somewhat jokingly but she suspected also somewhat seriously, “Know Your Role”. Since having this relayed to me, I have taken full possession of this term and will now be using it liberally any time I wish to tell ryeth to do my bidding.
