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 Stoned

The state of being so high that you begin speaking another language.

Friend 1: Yo, did you know that Marcel speaks Mandarin?
Friend 2: Yeah, but he only knows it when he's high as a kite, man. He was straight up Rosetta stoned last night.
