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 

A song by Tool, In which a man shows up in a hospital were the staff can’t find a single thing about him. 1 doctor, Dr. Larson, asks what’s wrong. The man Reluctantly answers with a tale that belongs in a scuffle-if story about how he was tripping on drugs then all of the sudden an alien ship he described as a “ Flaming stealth banana” and how he was elected by the alien to be the “Chosen one”. The chosen one is the person who will warn the world of incoming Armageddon. Then he forgets what the alien told to him, Which sends him into a fit of him shouting “Don’t Know, won’t know”, He then yells “ God Damn! Shit the bed!” Then the song ends, and nothing else is known about what happened.

I listened to Rosetta Stoned and it was weird as shit.

Rosetta Stoned 

An acute condition that occurs while hanging out with native speakers, in which you realize that all of the hours you logged with your Rosetta Stone software in preparation for your trip to Mexico are disappearing from your consciousness as your new amigos keep serving you tequila. The surest sign of this condition is the glazed expression on your face when someone asks, "Como se llama?"

Last night I met a lot of nice folks at a bar in Mexico City who got me so Rosetta Stoned that I could not remember how to ask, "where's the bathroom?" in Spanish.

When you are so high you think you can understand another language when reading the subtitles of a foreign film

After an evening of hot boxing the abandoned car the guys gather around to watch Paprika.

Rosetta Stoned 

Someone you can barely understand when they are stoned, or someone who tries to speak a different language when stoned.

It's hard to understand Ben when he smokes to much, he gets Rosetta Stoned.
