Meaning
A jagged burst of red, orange and yellow, like the “boom” panel in a comic book. It represents an explosion, a crash or a sudden impact, and by extension anything that hits with force or excitement.
People use it for dramatic reveals, big announcements and hype: “New collection drops Friday 💥” It also illustrates a literal bump, a headache or a mind-blowing idea. Marketers love its energy, but scattered across every line of a post it quickly turns noisy, and after real accidents or violent news it is best left out.
