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.
