My guess was:
Next person is currently playing a game that isn't in English.

That is, the game that the next person is playing is in a language other than English. (For example, the game I am playing right now, Wizardry Gaiden 4, is (mostly) in Japanese.)

The next person shouldn't try to explain things to me, especially when they're in negatory territory (if you say it just right, it rhymes).

Again, you are ignoring my guess. You are supposed to post whether the guess was correct or not.

And what are you going to do if I don't, neg me?

Next person has cooties.

Again, you are still ignoring my guess.

I was just playing the Czech puzzle game Vlak. Granted, none of the text in the game is all that important, but if I go to the Czech Republic, I could probably find a train station :P

The next person has used the Internet every single day for the past year.

nope. kinda impossible. unless i stop working , stop sleeping and stop eating. no NEETs allowed in asia unless you're japan.

next person wears a funny hat and wakes up drunken from drinking 4th-rate aussie wine screaming A DINGO ATE MUH BABAY!

No... I quit drinking years ago. I don't drink anymore, not even socially. Unless i am seriously upset, like from my latest internet dates, for example, after which i gulped down some good old rum to help me come to, recover from the shock and regain my senses. I even tipped the waitress a hefty sum, from the money i was planning to waste on that fat tub of lard, which ruined my evening and treated me like sh*t.

Next person smokes cigarettes that they themselves roll.

No. Cigarettes are disgusting and dangerous to those around the smoker; therefore I consider smoking cigarettes to be an immoral act under any circumstances.

Next person avoids both alcohol and caffeine.

No. I love caffeine. But yes to the other.

Next person is being punished unjustly.

Yes. Just look what's happened to my Rep here!

Next person's avatar doesn't include any color similar to red or orange.

Define similar.

Next person owns, or has owned, an exotic pet.

Hedgehog! I tamed a wild one once, but my stupid dog stomped it to death at night; i found it dead next morning come. Since then, i only feed them, clean them and send them off, never to get too attached to one of those, ever again.

Next person has experimented on themselves with traditional medicine from herbs and roots that they themselves crafted!

Your dog "Stomped" or "chomped" the hedgehog to death?
How big of an elephant is your dog?

look at this

Ah and yes i'll do some sort of traditional medicine
using a mix of alcohol and propolis (dont have bees on my own but a collegue has)
to get more resistive to cold and flu in the bad weather season.
5 till 10 drops of the mix every day in the morning on a sugar cube
- it works - at least i hadnt a real bad flu for several years now
I also drink self hand-picked lime blossom tea when i got a sore throat

Damn forgot: Next Person is a fishermen - and you all know the century old chinese saying:
A Fishermen is a lucky men.
(or was it maybe: Give a man a fish and he will eat for a day. Teach him how to fish and he will sit in a boat and drink beer all day)
