When a man masturbates and ejaculates and the sperm (a.k.a. nut) runs down your knuckles of the hand of which he was mastubating with.
Joe: Hey man did you fuck kelly last night?
Drew: Nah, bro she said she didn't want to at the last minute.
Joe: Damn that sucks. So what did you do then?
Drew: Well since she gave me blue balls I had to masturbate to relieve stress, and I accidentally gave myself Nut Knuckles.
Josh: You didn't have to tell me that.
Drew: Hey man you asked.

A popular variation of your typical knuckle touch/first bump with added, repeated horizontal motion so that both party’s knuckles gently grade against each other, thus creating a slight dusting effect. Note: it is vital that each participant exclaims in a high-pitched voice, “knuckle dusta” as they engage in said knuckle dusta.
