Pauly Shore is the lingustic genuis who brought us "axing the weasel." It is a reference to masturbation, a violent form of masturbation. Like Pauly Shore's short-lived film career the phrase doesn't exactly make sense.
When I'm horny and angry at my penis, I pop in "Encino Man" and start axing the weasel.
