The outburst from Steve-O began when Margera posted a throwback photo of himself sitting between Steve-0 and Johnny Knoxville, their Jacka** co-star.
Knoxville has also had a rocky relationship with Margera, who sued him for wrongful termination from the film Jacka** Forever in 2021, which he later dropped. Margera chose a rather controversial caption for the picture, which has been deleted.
"One arm is a best friend who had my f***ing back all along, another arm is a poser. A pro creation thief. If Jeff Tremaine was in this photo, he would be to greedy to fit."
