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.

Greystanes 

A suburb located 29km's west of the Sydney CBD. Locals like to refer to it as 'The G' as an attempt to make it sound a cool and hip place to reside/hang out but everyone else in sydney knows that Greystanes is literally the worst suburb in sydney.

The locals have bad reputations for stealing cabs from other commuters in the Kings Cross area and verbally abusing anyone who is either

a) not from 'The G'

or

b) speaks ill of 'The G'.

Locals generally have terrible dress sense and enjoy wearing horrific and mismatched accessories such as old school suspenders with cheap jeans and polyester shirts.

This place is worse than greystanes
