To defecate, out of necessity, in a bizarre location, such as on the beach in an ocean cove
Bob: I have to poop so bad, but there are no bathrooms on this private island.
Sarah: Perhaps you can go in that secluded cove. Just sit down in the ocean and drop a nickel.

To make a dicision with complete disregard to common sense.
Understanding that your better judgment tells you to get plenty of rest before tomorrow mornings meeting, you decide to drop two nickels in a bucket and join your friends for happy hour.

Making vague comments about someone's dirty secrets or hinting about bad behavior. Similar to drop a dime, but not as obvious, direct or complete.
"Dude, would you stop dropping nickels to my girlfriend about what I was doing last night? You're gonna get me busted for two-timing her!"
