A very specific type of
Glasgow Celtic supporter, they are extremely paranoid about anti Celtic bias and are known to spout extremely convoluted
conspiracy theories, much to the amusement of the rest of
Scottish football. The term refers to a wolfs despairing howl that goes unanswered, much like this area of the Celtic supports complaints. Not all Celtic supporters are moonhowlers but they are a very vocal group of supporters that give the club a bad name.
"Do you see that!? The referee should have gave Celtic a penalty! Another Rangers supporting referee!!"
"It looked soft mate, if all the
referees support Rangers then how did Celtic win 9 league titles
in a row?"
"We won them despite the biased the referee's, we were too good to be cheated"
"You're
starting to sound like a moonhowler John"
