Paddy Cakes - a nickname for UFC Champion Conor Mcgregor in middle-school.
The nickname Paddy Cake was given to Conor McGregor by the school's worst bully, who thought he was tough because he could hold his breath for five minutes.
The bully said, "You're just a Paddy Cake who thinks he's the king of the castle."
Conor's friend whispered, "You're gonna get it for being a Paddy Cake."
Conor wrote in his diary: "Paddy Cake is the worst."
