what does "tiddley-poo" and "four sheets to the wind" mean. And President George W. Bush, no less, and by his own admission, was smashed, or tiddley-poo, or four sheets to the wind a good deal of time from when he was sixteen until he was forty。(From < A Man Without A Country>) I know he is joking about Bush's addiction to alcohol. But what does "tiddley-poo" and "four sheets to the wind" exactly mean? And why the sequence, from "smashed" to "tiddley-poo" to " four sheets"?Does it mean that he was so drunk that he shit and pee on bed ?
