I guess it is meant to match 'leet'? I'm not sure why there's the option for 3 letters, though ….
EDIT: Ah, got it (I think). It's referring to being a polymath hacker: "Just another vim hacker", "Just another perl hacker", "Just another Unix hacker", etc.
Many of these can be shoehorned in: Mac, -, -, cpp, gcc, -, -, ghc, ogle, -, -, -, Lisp.
(I know that Scheme is not the same as Lisp, and that a language is not the same as its compiler; but would you have "Just another .* hacker"? :-) )
(Also, I can't remember if 'ogle' is actually a tool in the Go language toolkit, although I seem to remember someone saying that it should be. Googling 'go ogle' doesn't have much luck, since Google thinks it knows what I really meant.)
