Like a typo but when mis-clicking with a mouse instead of mis-typing on a keyboard.

For example, you click the wrong link on a web page because the links are close together. This can sometimes have disastrous results, such as in accidentally clicking a 'buy it now!' button.
I nearly won the auction but I made a clicko at the last second!

Get the clicko mug.
Similiar to a typo except that you just clicked the wrong box and sent someone a message meant for someone else, or bought something or signed up for something that you didn't intend to. Could also be used as an excuse
Dad- "Where did that Porsche 911 in my driveway come from?"
Son- "Sorry, I was surfing (ebay) and accidently hit "buy it now," my clicko!"
Dad-"you're so effed"

When you click something you didn't mean to click.

Like an ad or something stupid.
Whoops, I clickoed on the "Shoot the monkey and win a free house ad"
