23 Skidoo
23 skidoo (sometimes 23 skiddoo) is an American slang phrase popularized during the early 20th century. It generally refers to leaving quickly, being forced to leave quickly by someone else, or taking advantage of a propitious opportunity to leave, that is, “getting [out] while the getting’s good.”
Doesn’t look to me like -23 is linked to anyone or anything. — just out there on its own. Or am I missing something?
