[FOXING]; (verb) To Fox
The art of going into places you shouldnt, taking things you [oughtnt] to, and doing things that in most countries are probably just a tiny bit illegal. Acts are usually performed while under cover of darkness, with an MO directed in a more lighthearted vein, as opposed to an operation of terror or destruction. Can also be used to describe an outing of mischief. Similar to reality hacking, urban infiltration/[urban exploration], and parkour, but with the added bonus of finding random items to be purchased as trophies for well-run missions.
