a recent (within the last couple of months!) conversation with my boy
kellen: oh sit (as he drops something on the floor)
me: what did you just say?
kellen: oh shit (a little more clearer, with a big grin on his face)
me: kellen, that's not a nice thing to say. why don't you say, oh, man!
kellen: oh shit, man! (with an even bigger grin on his face)
me, thinking to myself: oh shit!!!
