4 the thing/matter which makes one feel angry

[David L.]

'a good hiding' : 'hiding' here means a physical beating.
"You cheeky devil! Just wait till your father gets home. You're in for a good hiding, young man!"

'red rag to a bull' : it was thought that bulls would react aggressively to the colour red. So, the idea of somebody waving a red rag at a bull would be sure to get the bull to charge and try to gore them. As as idiom, it means that you what you are saying or doing/going to do is sure to make another person angry.

'donkey work' : donkeys are traditionally used to carry loads of goods on their poor backs - before cars and trains, and now, when usual forms of moving supplies is not possible because of the terrain and only donkeys can, say, climb up and down a very narrow path to the bottom of the Grand Canyon. So - for a person to be said to be doing the 'donkey work', he is being made to do the laborious, boring part of a job.
