Lúcio Correia dos Santos is a Brazilian DJ and support hero in Blizzard's Overwatch, released in 2016. His alternate fire, Soundwave, knocks enemies back with a short-range blast from his Sonic Amplifier, and players quickly nicknamed both the ability and its sound a boop. Environmental kills from bridges and ledges made the clip a staple of highlight reels and montages. The word also matched the wider internet boop meme for a gentle poke, helping the sound spread beyond Overwatch into general reaction edits.
About this sound
Lucio's boop sound effect from Overwatch, the short voice line and pushback whoosh players use for knockback kills, fails and playful reactions.
Lucio's boop is a quick, cheerful vocalisation paired with the thump of his Sonic Amplifier pushing an enemy away. The clip is very short, just the word delivered with upbeat energy followed by a soft airy whoosh, which makes it instantly recognisable to Overwatch players. In edits it lands as a light punchline rather than an attack, turning a shove, a fall or an unexpected exit into a joke. The brightness of the delivery keeps the moment playful even when someone has just been knocked off the map.
