Definition of "Ivor"

I'd weave through the throng — scanning for empties to return while flirting, sniffing out kids smoking grass and sharing smokes with Ivor and Carl on the door. With a name like Carl you can imagine a six-foot tall and wide bouncer, but Ivor...I couldn't but help to think of the name as belonging to a skinny Welshman getting sand kicked into his face. His name didn't do him justice — this guy was almost as big as Carl and probably faster with his fists.
