Terrainium 

A random person that is stupid and is atrociously loud often being a big dumb and also changes their laugh for some reason.

Terrainium just rushed into objective and got 3 kills and died just like the last three rounds.

terranigma 

Arguably one of the finest games ever created. Though like Seiken Densetsu 3 it never made it stateside, it was big in the UK and among the many gamers in America that have managed to get a hold of it, myself included.

Terranigma is the third and final installment in the "Gaia series".

Terrarium

A self-contained environment, usually with only plants inside, that was originally called a Wardian Case. They can be made out of fish tanks with flouroscent hoods, clear empty wine bottles or demijohns, or something as simple as a fish bowl. If there are frogs or herps and/or an exposed pool of water inside, it is considered to be a vivarium, but you can still call it a terrarium.

I love to just stare at my terrarium.
