Straight from the Big Fella

I'm like the Pythagorean theorem. Not too many people know the answer to my game.

Fan-sourced! After signing with Boston in August 2010, Shaq tweeted "Hello green town" and asked Celtics fans for a new nickname. "The Big Shamrock" was one of the top vote-getters, and by October the AP said "The Big Shamroq" was the leading choice.

Left out: nicknames that show up in lists without a documented origin, plus a few the Big Fella would probably rather we skip.
