look up any word, like the eiffel tower:
 
1.
what are you up to? --> whatcha up to? --> chupta?

the word derives from the sound you get when you pronouce that phrase quickly, or perhaps speak with a residual oklahoma accent.

coined by okie at mit. it may be spreading on the mit campus. apparently it's big in maine, too.
generic screenname: chupta?
