stealing someone's thunder

Claiming unearned credit

Stealing someone's thunder means taking credit for another's idea or diminishing their moment by doing or announcing something first.

The phrase comes from an 18th-century playwright whose sound-effects technique for stage thunder was used without permission by a rival production.

She announced her engagement at my birthday party and completely stole my thunder.
