static electricity
An electric charge that builds up on the surface of objects, commonly experienced as a small shock when touching metal objects or other people, especially in dry winter weather.
静電気でバチッときた。
I got a static shock.
Combines 静 (still, static) + 電気 (electricity). Very commonly discussed in Japan during the dry winter months. Common collocations: 静電気が起きる (static builds up), 静電気が走る (a static shock runs through), 静電気防止 (anti-static), 静電気除去 (static removal). Products like 静電気防止スプレー (anti-static spray) are popular in Japan.
