The bit works on two things: the pose and the chant. People plant their feet, pull cupped hands back to their hip as if holding an invisible ball, then draw out 'Ka, Me, Ha, Me' before thrusting forward and screaming 'HAAA'7. The joke is that the charge-up takes forever while the actual blast lasts a split second, exactly how it plays in the show4.

Online, the Kamehameha format splits into three flavors: raw convention and bedroom imitations1, After Effects composites where the caster actually fires a glowing beam2, and mock-scientific explainers picking apart what a real wave would do to a target5. All three lean on the same instantly recognizable posture, which is why any Dragon Ball fan can spot the reference in about half a second.

The classic form is a set piece, not a one-liner. People typically plant their feet shoulder width, cup both hands at their right hip as if gripping a softball, and stretch the syllables 'Ka, Me, Ha, Me' as long as they can before shoving both palms forward and yelling 'HAAA'7. Group versions pair one person doing the charge with a friend mock-flying backward off the beam, which is the format most convention clips lean on1.
