This phrase has commonly been misinterpreted as the complete opposite of its actual meaning. when someone asks "Are you mental?!" it means that they are asking if you ARE in fact mental and your brain is functioning PROPERLY. In todays society it has been disregarded as a phrase that implies being "mental" is a bad thing, when in fact being "mental" means your brain is working correctly.

Derives from the adjective temperamental: a person used to sudden changes in mood.
Because Americans can't spell, the word has been shortened to the last two syllables, but everybody has forgotten about the original spelling. That's why shortening words is always a bad idea.

Adj. A word used to describe an individual who does something dumb, or so stupid that they should be considered (or are) mentally ill or retarded. Can also describe someone who is just dumb in general or makes bad decisions all the time. Or, it can be used as a noun to describe someone who is ACTUALLY mentally ill. However, this can be considered offensive or derogatory so use at your own risk. Lastly, it can be used as an adjective to simply describe something that's crazy or mind-boggling.
