Not to be confused with your ex, the letter X is the 24th character in the alphabet, and third last in the alphabet. Just like your third last relationship because you needed a little time to "think" about yourself.

There’s a few X names out there who are just TRASH! They are really nasty friends and will turn their back on you before a snap. You may have friends with the starting letter X and maybe they aren’t this definition. But the one I’m talking about OH trust me STAY AWAY!
