MEANING:
Phrase: whatever, (adjective) identical, exactly the same.
DERIVED FROM:
Aivan means ”exactly,” ”precisely” or ”totally.” Or as an exclamation ”indeed!”
Sama means ”the same.”
EXTRA CREDIT:
Hintaa meinaan means ”I mean the price.”
The advertisement is a bit of a play on words as ”aivan sama” means both the polite ”exactly the same” and the teenage exclamation of ”whatever!”
