A term used when you're really angry with something that has happened in a short amount of time and then you take corrective action to make sure that something related will never happen again. (Being angry for a short amount of time like 20 seconds).
When someone online performs crap on your team in a game and you had to perform better than them, you also take into account their overall performance then accumulate it all at once in a snapshot fury and take that corrective action.
"Urgh, he's so fricken crap, i'm going to have to remove him!"
to go on a tour and take a quick snapshot experience of a tourist attraction, not even beginning to experience anything beyond the viewfinder.
Nick- I want to go on a european trip of backpacking and hitchhicking.
Matt- Thats a great idea, just don't partake in any snapshot tourism.
Nick- Don't worry, Im not one of those people.
More common spelling of the "Snapshotday" word, which came from the "It'sWednesday, my dudes" meme. Used among Minecraft players for snapshot release days.
