A slang term for the anus, or as I like to call it, butthole. It is the tight sphincter that cuts the pooh as it leaves your body. Sometimes it is also the opening that men like to place their cocks inside for great pleasure.
After taking a dump and wiping my pooh cutter, Billy lubed up and slid his hot cock inside me for some hot pooh cutter sex.
