buttock exception

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.
