chaa daa

its like shortening cha dude which was shortened (or mispronounced) from yeah dude!

if you were gonna say it but you didnt know how, it would probably be spelt (in pronouncing version):
chiah dah

(note: do not pronounce like chia from those chia pet commercials because then youll just sound stupid)

Buddy: dude this rocks!!!!

you:chaa daa
