There once was a piglet named Boss Hog
Who spent all of his days on a log.
He sat there all day
While his friends went to play
'Til one day he was lost in the fog.
Meaning: There are two distinctly different meanings of this term. The first is cockney rhyming slang for beer. The second meaning is a mess or muddle.
Origin: The earliest origin is from the cockney rhyming slang. From W. Barrett's Book Life and Work Among Navvies in 1880: "Now, Jack, I'm goin' to get a tiddley wink of pig's ear." I'm not sure what the tiddley wink is referring to but he's definitely telling Jack he's going to get a beer.
