X

Not El-Hajj Malik El-Shabazz—I went to high school with a wholly whitebread girl with the middle name of X, just X, just like Homer J. Simpson's middle name is just J. It was pronounced "ex," not "zuh" (as in Xavier) or "jhuh" (as in, I think, Xiomara and Ximena); it was, in other words, just X of the Roman alphabet, not X of Cyrillic (usually transliterated as "kh," and close to "ch" [as in Chanukkah] in sound, in my unprofessional opinion [very unprofessional, indeed, incorrect — ed.]). And let's not forget the X of Mandarin! No, let's! X. X. X. Just X.

If she changed her name, she could be ex-X. And someone she breaks up with could refer to her as "my ex, ex-X." And so on, x cetera.
