Each column has a group of words with a commonality. I call it 1, 2, 3 words. What are they?

On April Fools, my friend has given me a sentence and said it's a prank, but I didn't understand it. I asked "What is this?", he mentioned "A joke.", so I was confused what he meant as a joke. It says: //3\32 60////4 6!\3 '/0L| L||*, //3\32 60////4 137 '/0L| ]0\//, //3\32 60////4 2L|// 420L|//|]...
