High voltage (lightning bolt) is used far more often for energy, excitement, or intensity than literal electricity — 'high energy,' a fast/shocking moment, or emphasizing speed. It's also a Pokémon-adjacent cultural reference for many millennials given its resemblance to Pikachu's signature move imagery, though that's coincidental rather than intentional design.
