Warning…if you watch the video below just know it has some cursing. Aaron Lewis drops a few F-bombs, directed at the crowd who was talking during his performance. And, admittedly, it does sound like some are heckling him a bit.

However, this isn’t the first time Aaron Lewis has done something like this during a live show. According to TMZ he got in a similar altercation in Texas with fans who were speaking Spanish last month. And not long before that he called out a “heckler” right here in Indianapolis.

Again, language warning. Probably not safe for work or around kids.
