The act of excepting or excluding the buttock(s) from legal
definitions of battery or criminal
sexual conduct.
See, 609.3451 CRIMINAL
SEXUAL CONDUCT IN THE FIFTH DEGREE "For purposes of this section, "sexual contact" has the meaning given in section 609.341, subdivision 11, paragraph (a), clauses (i), (iv), and (v), but does not include the intentional touching of the clothing covering the immediate area of the buttocks."
Senator Al Franken is not guilty of criminal
sexual conduct when he grabs ass because "the
immediate area of the buttocks" is excepted by
definition in the relevant criminal statute..you know...the buttock exception. He's just a a dirty old creep.
