JC Slapper refers to the Welsh Light Heavyweight boxer, Joe Calzaghe.

JC refers to Joe Calzaghe's initials while Slapper describes his style of fighting. Instead of throwing punches like a man with a closed fist he "slaps" while apparently effective, it still makes him a pussy.

JC Slapper, while holding a record of 46-0, his record is highly padded and very protected.
JC Slapper fighting 40 year olds does not make him an All Time Great
