Psionic shower

A psionic shower is a telekinetic ability exhibited by the Psyches and by Empath Smurf in the EMPATH: The Luckiest Smurf that enables them to cleanse themselves without needing to undress themselves by simply emitting a pulse of mental energy throughout their own bodies that purges them of all dirt and body odors. It is usually done when a Psyche is away from Psychelia, where cleansing chambers are used.

The term is a play on "sonic shower", a piece of technology that appears in the Star Trek franchise of stories.
