値段設定バグ

• Reading: ねだんせっていバグ
• Romaji: nedan settei bagu
• Kanji breakdown: 値段 (price; 値 = value + 段 = level) + 設定 (setting; 設 = establish + 定 = fix) + バグ (from English 'bug') → price setting error/glitch
• Pronunciation: /ne.daɴ.set.te.i.ba.ɡu/

Meaning

When the price is so unbelievably cheap it seems like a software glitch — used to praise ridiculously good deals.

値段設定バグ (literally 'price setting bug') is used when something is so affordable relative to its quality that it seems like the pricing system must be broken. It's internet-born slang that frames exceptional value in tech/gaming terms (a 'bug' or 'glitch' in the pricing). Common in food reviews, product recommendations, and social media posts about surprisingly affordable finds. It's always used positively — high praise for the business offering the deal.

Examples

1. このランチ800円で食べ放題とか値段設定バグってない？ An all-you-can-eat lunch for ¥800 — isn't the pricing glitched?
2. 品質考えたらこの値段は値段設定バグだよ、買わない理由がない。 Considering the quality, this price is a total pricing bug — there's no reason not to buy it.
3. この美容室、カット1500円って値段設定バグすぎるでしょ。 This hair salon charges ¥1,500 for a haircut — the pricing is way too glitched.
