X is in meXico, where "boys like you" went.
("Fence" and "went" are good examples of "half-rhymes". Another one used was "lasso" and "wrestle". Same number of syllables and similar vowel and consonant sounds, even if they are not a traditional rhyming match. Totally acceptable in most poetry, and in this game. Also note the example of the cheated "X" in "meXico".)
