To sign 'boom', start with both hands in closed fists (S-shape) raised near shoulder level, with your palms facing forward. Bring both fists down forcefully and abruptly, ending in front of your lower torso. The movement should be sharp and sudden to convey the heavy impact of a 'boom' or an unexpected event.
To express this concept, you would sign 'thunder' followed immediately by the sharp, downward motion of 'boom'. The forceful, abrupt movement of your fists perfectly captures the sudden, loud impact of the sound, making the description much more vivid.
Use this sign to represent the suddenness of the unexpected event. You would perform the sharp downward strike of 'boom' right before signing 'power out' to emphasize how instantly and surprisingly the lights shut off.
After signing the action of the car crashing, you can emphasize the severity of the impact by adding the forceful downward strike of 'boom'. This adds dramatic weight and shows the sudden, heavy force of the collision.

While this specific sign effectively conveys a sudden impact, a heavy drop, or a 'bam!' moment, an actual fiery explosion is often signed a bit differently. For a literal explosion, signers typically start with closed fists that suddenly burst open into spread fingers (5-hands) moving outward to mimic expanding debris.
You don't necessarily have to mouth the exact English word, but ASL uses facial expressions to show intensity. It is very common to use a mouth morpheme—like puffing your cheeks slightly and releasing the air, or making a tense 'pah' mouth shape—to match the sudden, forceful nature of the sign.
No, this specific sign represents a physical impact, a loud noise, or a sudden, surprising event. If you want to talk about an economic boom, business growth, or a sudden increase in popularity, you would use entirely different signs related to 'increase', 'success', or 'taking off'.
