Oklahoma State's Marcus Smart lost his sh*t on Saturday with just seconds left in a men's college basketball game against Texas Tech.

After trying to block a dunk, he stumbled backwards and fell into the crowd. While he was being helped to his feet, a Texas Tech fan yelled something at Smart that set him off, causing him to confront the guy and shove him. He had to be restrained by his teammates, but continued to freak out about the incident.

Smart has apologized for the incident, to both the fan and everyone else involved, but has still been suspended for three games.

It is still unclear exactly what the fan said to set him off, but that doesn't really matter.

This was a stupid move on his part.
