http://en.wikipedia.org/wiki/Rod_Smart"He Hate Me" is the phrase {Rod} Smart chose to place on the back of his Las Vegas Outlaws football jersey during the one and only season of the XFL (2001). Though most sports organizations allow only a surname or first initial and surname to be placed on the back of a jersey, XFL rules permitted players' jerseys to be stitched with whatever words they wanted.
Smart explained the origin of the grammatically non-standard phrase in a January 30, 2004 article with the Milwaukee Journal Sentinel as, "Basically, my brother's my opponent. After I win, he's gonna hate me. It is what it is. It's a saying I was saying when I'd feel something wasn't going my way. For example, (when) I was on the squad in Vegas and coach was putting other guys in, (if) I felt I'm better than them, you know, hey, 'he hate me.' See what I'm saying? Give me a chance. That's all I ask. It came from the heart. Within. The way I felt. My buddy Greg Kates always used to use it, so I took it from him."<6>
When Smart and the Outlaws played divisional rival Los Angeles Xtreme, two Xtreme players put "I Hate He" and "I Hate He Too" on the back of their jerseys to express their disdain for Smart. In a later game between those two teams, those two players changed their nicknames to "Still Hate He" and "Still Hate He Too". The curious maxim also caught the eye of American audiences (as well as Smart's future Carolina Panthers teammate Jake Delhomme, who named one of his thoroughbreds, "She Hate Me").<[br />
