Collymore just shouts all the time,in the playground bully way in that he is bigger than you and louder so he is right.He hopes by using these tactics he wins the argument.It might work in the playground but it doesn't come across well on radio.
I remember years ago he was on one of those awful reality type shows and he got into an argument with another guy in there.Collymore ends up ripping off his mic and offering the guy out in the garden off the camera.Again he was bigger and heavier than the other guy so was probably onto a winner, he is a cretinous bully.
