A bit of slang originating from the depths of Chicago University (purportedly by a one Tyler Brown). It is essentially a positive term in the vein of cool, mad, awesome, hip, ill, wicked, narly, tubular, sweet, bodacious, bitchin', killer, phat, rad, and perhaps righteous (if you happen to still be in the seventies).

Pronunciation: Both syllables rhyme with the word "dough." Emphasis is on the first syllable.

The variant Choko Ono is sometimes used for special emphasis (this being a clever pun on the name of Yoko Ono).

Example: " Deltron has mad beats; his new song is so choko."
