What does zap mean?
Zap is an informal but highly expressive English word for a sudden burst of energy and the action it produces.

Zap is an English coinage that appeared in the mid-20th century, probably in American comic strips and related science-fiction contexts.

From that specialized dramatic use, it spread into general language for rapid electronic communication, television channel changes, and forceful destruction.
