Question 3

Is "boom off" formal or informal?

Accepted Answer

"boom off" is register-neutral — appropriate in both casual and formal contexts. Relatively rare and mostly found in literary or descriptive writing to convey the resonating effect of a very loud sound, such as a cannon, thunder, or explosion. The particle 'off' suggests the sound launching or reverberating away from its source.
