the opposite of abcd, in more ways than one.
dcba = desi confused by america, "desi" being the indian word for a "native of india". refers to an indian guy/girl who tries to keep up with trends in usa and tries generally, to come across as a very americanised sort of person.
btw, abcd = american born confused desi.
last time it was a metallica tee-shirt. now its an ear ring and punk hairstyle.
