From The Stick Jock’s Dictionary – A player is said to be “riddled” when they are hit more times than strictly speaking were needed to make them call a death. The phrase was made popular by Arthon and Rand, and comes to us from this scene in the movie “Michael Collins”:

Made the front page.
What does it say?
"Dublin Detective Riddled With Bullets".
"Riddled"? Riddled?
Why are you riddling people?
Ten bullets, when the one would do?
To make sure he died.
Lads, try and remember they don't grow on trees.
- What don't they grow on? - Trees.
Boys, you did well. But go easy on the riddling.
