Meaning

To panic, be flustered, or lose composure when overwhelmed — describes a state of frantic disarray.

テンパる describes that flustered state when you have too much going on and can't think straight — panicking before a deadline, blanking during a presentation, or fumbling when put on the spot. It carries a slightly self-deprecating, relatable tone. The word is universally understood and commonly used when recounting stressful moments.

Examples

1. プレゼンの途中で頭真っ白になってテンパった。 My mind went completely blank during the presentation and I panicked.
2. テンパってるときに話しかけないで。 Don't talk to me when I'm freaking out.
3. 初めてのバイトでテンパりまくった。 I was a total mess on my first day at the part-time job.
