To Keeley out is to either arrange a meeting with enthusiasm, only to not turn up (or as skaters and hippys might say; bail') , or to attend said meeting, only to leave shortly afterwards, usually to watch some inane programme on television.

The usuage originates from famous Physicist Leslie Keeley, who invented a medical treatment for alcoholism, but spent so much time performing operations that she would often forget to hang out with her bois. She died in 1965.
