Rosetta-stoned 

Feeling that you "really know" a language; often caused by excessive, regular use of the Rosetta Stone Software. Common side effects include: strong sense of euphoria; spinal problems due to nose constantly in air; severe lingual confusion; and loss/gain of friends (outcome may depend on social class).

My friends and I like to get Rosetta-stoned on the weekends; usually in my parents' basement. They always leave feeling a little hazy-- it's never fun to have to speak your native tongue after THAT.

Rosetta Stone

A pretty good software that will make the green owl very very angry if you use.

Green owl: It's time to do your Spanish lessons!
You: No thanks I'm using Rosetta Stone.
Green owl: Don't fall asleep
