My personal favorite has always been TIMTOWTDI (There Is More Than One Way To Do It).

In fact, in a double sense this acronym represents everything I like about perl: first, the fact that the language isn't as strict as others and allows for a lot of personal idiom and expression in code; and second, the fact that perl has a great and fun-loving community behind it. I mean, really, who else would come up with such a ridiculous acronym...

FWIW, I just searched google groups and TIMTOWTDI was used in 24 threads in comp.lang.perl.misc over the past year... I would have guessed more.
