JJ is an acronym for the Jazz Jackrabbit series of games, or rarely, the title charcter, or first in the series, although the first one is mostly called JJ1. Also used are JJ2, for Jazz Jackrabbit 2, JJ3, for Jazz Jackrabbit 3D, and JJA, for Jazz Jackrabbit Advance.
Craig went to bed after a long refreshing game of JJ2. Earlier in the day, he had been playing JJ1, JJ3, and even JJA. As he fell to the dark aura of sleep, he had only one thought. "I love the JJ series.."
