Lance Stephenson is demanding an end to the sex toy-throwing chaos at WNBA games -- not just out of respect for the players, but also for the young fans in the crowd. The longtime NBA star made things crystal clear to TMZ Sports this week ... following a fourth incident where a dildo was launched onto the court during a W contest.

A spokesperson for the group told USA Today, members started throwing green sex toys to coincide with the launch of the meme-coin, which was created the day before the first incident. The group wanted to use the "viral stunts" to garner attention.

A bizarre and decidedly crude string of incidents has eclipsed the action on the court in the WNBA this week and top figures in the league are calling out the disrespect they’re feeling as a result.
