geocashing 

A social media game where participants decipher clues in order to locate hidden cash, usually in the form of currency. A riff on geocaching. As made popular by the #hiddencash game which originated in San Franciso, CA in May of 2014.

I am going geocashing for hidden cash around town once the new clues have been tweeted.
