rocktacious 

adj. Excellent, fantastic.

Derived from the verb "to rock" (to be excellent). Appending the common English suffix "acious," the word becomes an adjective meaning roughly "the quality of one who rocks."

May also be used as an interjection.

Rocktacious! I just bought a whole chocolate factory with no money down!

I rock; therefore, I am rocktacious.
