Any good anagrams for knuckling?

Fingering is typically the use of fingers or hands to sexually stimulate the vulva (including the clitoris) or vagina. Vaginal fingering is legally and medically called digital penetration or digital penetration of the vagina. Fingering may also include the use of fingers to sexually stimulate the anus.Fingering may be performed on oneself (masturbation) or by or with a sexual partner. When performed on the vulva or vagina by a sexual partner, it is a form of mutual masturbation, and is analogous to a handjob (the manual stimulation of the penis). It may be used for sexual arousal or foreplay, constitute an entire sexual encounter, or be used as a form of non-penetrative sexual activity.
