Bruit de bouche laser is French for a mouth-made laser sound, a simple vocal trick that has long been used by children, beatboxers and amateur performers to imitate ray guns without any equipment. Online, short clips like this circulate as ready-made soundboard effects because they are instantly recognisable, easy to reuse and free of the polished feel of studio libraries. Their charm lies in that human imperfection, which makes them ideal for comedy, gaming and short-form video, where a quick, playful zap can sell a joke in under two seconds.
