Louisville resident Boris Simic was so angry at his dad for sexually neglecting his mom that he actually walked onto Kentucky's heavily trafficked I-264 in the pouring rain.

Simic's mission: to find his father (who lives 10 miles away) and kick his you-know-what.

Police were quickly called to the scene after cars begin swerving around Simic to avoid an accident. They found him shirtless and, as you might imagine, very, very angry. In fact, when once officer tried to get him off the road, Simic replied, "Go f*** yourself." Shortly after, Simic was arrested for disorderly conduct.

According to police arrest records, Simic told officers he was angry at his dad because "his father would not have sex" with his mother.

We guess he's a mama's boy.
