Bandwagon Boxing Fan

Someone who only watches the massive PPV Boxing fights and doesn't watch any form of boxing on a regular basis. They act like experts in the field of boxing, but have never had a competitive fight in the ring, never participated in any boxing training and lack any qualifications/merit related to boxing.

Person 1: I'm watching the boxing saturday are you? Person 2: No, I'm not a bandwagon boxing fan like yourself.
