Lil Boosie Fan Learns the Hard Way Don't Try to Jump on the Stage!

0304-lil-boosie-tmz-launch-01This public service message about trying to jump up onstage at a Lil Boosie concert is brought to you by his security team and the letters G, T, F and O.

An excited fan hell-bent on getting onstage with rapper Lil Boosie finally got his wish, but it only lasted a few seconds ... because the guy was quickly smacked back into the crowd.

The beatdown was delivered during a recent show in St. Paul, Minnesota. According to our sources, the fan was acting drunk and repeatedly tried to climb onstage. We're told Boosie ignored him, but security didn't ... and quickly sent the guy packing once he finally crawled onstage.  

We're told the fan was eventually kicked out of the show ... maybe literally.
