Sex kick

Mario and Luigi's neutral air.

A sex kick is an aerial kick that is strong during the initial thrust and weakens over time. They were first introduced in Super Smash Flash 2, though similar attacks exist in Super Smash Flash.

Most have low startup time, making them useful for stringing them quickly or disrupting combos; and long duration, which makes intercepting opponents with them easy.

There are moves that are not kicks that behave similarly, like Captain Falcon's forward aerial and some neutral aerials (like Peach's for example).
