noun
dirt cheap; ridiculously low price
Colloquial term emphasizing an extremely low price, often with a nuance of surprise or disbelief. Used in casual conversation and advertising.

激安 also means 'super cheap', but is more neutral and widely used in advertising. バカ安 is more colloquial and carries a stronger emotional tone.
格安 means 'reasonably priced' or 'bargain', often used in formal contexts like travel deals. バカ安 is much more informal and implies an almost unbelievable low price.
Compound of バカ (fool, idiot) and 安 (cheap). The prefix バカ intensifies the meaning, similar to 'stupidly cheap' in English. The exact origin is uncertain, but it likely emerged in casual speech.
