ブツブツ

• Reading: ブツブツ
• Romaji: butsu butsu
• Pronunciation: /bɯ.tsɯ.bɯ.tsɯ/

Meaning

Muttering or grumbling under one's breath — also describes a bumpy, pimply texture.

ブツブツ has two distinct meanings. The sound meaning describes someone muttering complaints or grievances in a low voice, barely audible but clearly unhappy — the kind of under-the-breath grumbling that's annoying to be around. The texture meaning describes small bumps on a surface, like goosebumps, pimples, or the rough surface of a strawberry. Both uses are common and easily distinguished by context.

Examples

1. また部長の悪口ブツブツ言ってるよ。 There he goes again, muttering complaints about the boss.
2. 腕にブツブツできて皮膚科行かなきゃ。 I got bumps on my arm — I need to see a dermatologist.
3. 何をブツブツ言ってるの？聞こえないよ。 What are you mumbling about? I can't hear you.

Usage Guide

Context: complaints, skin, texture, behavior

Tone: annoyed, descriptive

Do Say

• ブツブツ言ってないで直接言えば？ (Instead of muttering, why don't you say it directly?)
• ブツブツが気になるから薬塗ろう (The bumps are bothering me so I'll put some cream on)

Don't Say

• はっきり大声で話してる人に「ブツブツ」は合わない (Using 'butsu butsu' for someone speaking clearly and loudly doesn't work — it means low muttering)

Common Mistakes

• Not recognizing the texture meaning — ブツブツ for bumpy skin is just as common as the muttering meaning
• Using ブツブツ for loud complaining — it specifically describes quiet, under-the-breath grumbling
