geotrashing 

Like geocaching, but instead of following the rules of geocaching, the participant destroys/ and or steals everything in the cache, ruining it for everyone else

"Joey, I heard some douche bags went geotrashing and destroyed 3 of your geocaches!"

Geostashing 

Geostashing is similar to Geocaching, the only difference is your treasure is a secretly hidden stash of dank bud. Aww yeah! The location can easily be pinpointed using geocaching.com or any similar "site or app" The Golden Rule applies as well. "After finding such valuable gift, you must leave something of equal or greater value" (Usually a different strain) Leaving a greater value makes you a "GoodGuyGreg" leaving nothing or schawg makes you a "Scumbag (your name)"
The term was coined in an r/trees thread.

Hey fellow Ents here's another Geostashing mission for those in the Denver area, if anyone is interested the coordinates are "********" I left some Sour Diesel under a boulder next to the Deku Tree. If you meet the troll, the password is swordfish.

Geogashing 

Similar to the childhood pursuit of Geocaching. where one searches for hidden "caches" of treasure. Geogashers are given the rough location of a brothel and have to find its contents, the "gash". A brothel hunt.

After ten pints and two lines, Dan gave Sean the mysterious Geogashing directions, so he could empty his sack.

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.
