This is a word heard fairly regularly around our household, our funny way of expressing surprise at the itsy bitsy things that go wrong. Some examples:
This morning my husband dropped a small piece of his hard-boiled egg in his lap and immediately exclaimed, "HEY! That's not what I was trying to do!"
One time I was holding a stack of papers and one slipped out of my grasp onto the ground. As it wafted to the floor I said, "HEY! Come back here!"
Whoever happens to be near us when this happens thinks this is the funniest thing ever...it never fails to elicit a good chuckle.
