Also typically referred to as a womans anus in which she refuses to let get penatrated by either a penis or other sexual objects
All straight men consider the anus as a No Hole due to the fact that anal penatration is not a option under any circumstance!!!

Dave - "Damn man after that party last night me and Lisa went back to my place and there is no such thing as a NO Hole for that girl!!"
Brad - I told ya man, that girl is a FREAK!"
