A way of swearing, without swearing. Instead of saying "Jesus Christ!" you say "Jiminy Cricket!" Both words have the same initials. Of course, Jiminy Cricket was the bug in the Disney Pinnochio movie.
Jiminy Cricket, I wasted my money on that Mel Gibson movie!
What you say when something amazing flies by.
JIMINY CRICKETS did you see that?! A BLUEBERRY JUST FLEW BY!!
An old term for not saying Jesus Christ, thus not using Christ's(God's) name in vain and not breaking one of the 10 Commandments or blaspheming. Usually used with emphasis.

The term is older than the character from Disney films: a talking, singing, and fancy-looking cricket.
