Lane Kiffin has fully embraced the art of social media trolling, and his latest target is arch-rival Auburn.

While his attempted hashtag is not clickable, Kiffin captioned his photo of the Auburn exit sign with apparent references to USC’s national championship win over Oklahoma in the 2005 Orange Bowl (55-19) and Alabama’s 2015 win over Auburn (29-13). The first score is intended to remind Auburn fans of the 2004 season, in which the undefeated Tigers were left out of the BCS Championship Game. Kiffin was a Trojans assistant at the time.

The Auburn tweet follows Kiffin’s recent two-part troll of following multiple Tennessee-related accounts before posting “#RTR16” to caption a photo of a Knoxville interstate sign.

What would the college football offseason be without some social media smack talk?

Edit: An earlier version of the article stated both scores were references to Alabama-Auburn games.
