ツボ

• Reading: ツボ
• Romaji: tsubo
• Pronunciation: /tsu.bo/

Meaning

Sweet spot or funny bone — the thing that perfectly hits your sense of humour and makes you laugh uncontrollably.

Originally referring to pressure points on the body (acupuncture points), ツボ in slang means the specific thing that triggers uncontrollable laughter. When something hits your ツボ, you cannot stop laughing even if you try. The phrase ツボに入る (to enter the tsubo) or ツボにはまる (to fit into the tsubo) means something has hit your funny bone perfectly. Everyone has different ツボ — what is hilarious to one person may not affect another at all.

Examples

1. あの顔芸がツボに入って笑いが止まらない。 That funny face hit my sweet spot and I can't stop laughing.
2. なんでこんなのがツボなのか自分でもわからない。 I don't even know why this is so funny to me.
3. ツボ浅すぎてなんでも笑っちゃう。 Your funny bone threshold is so low, you laugh at everything.

Don't Say

• Not knowing ツボ浅い (shallow tsubo = easily amused) vs ツボ深い (deep tsubo = hard to make laugh)
