The Sheet has learned Impact Wrestling officials were very unhappy with Josh Mathews for saying "shoot yourselves" to the hosts of a podcast ... and he got a stern warning for the future.

Mathews got into with someone on Twitter  yesterday and told them, "Ohh, 'Real Shoot Wrestling Podcast!' Taking offense! 😳😳 Did you guys book a great 'SHOOT style promo!' You should really shoot yourselves."

Sources with direct knowledge tell us management saw the tweet and weren't happy at all, something they quickly expressed to the play-by-play announcer for future reference.

The tweet has since been deleted. However, Josh still has another up that features a screengrab of his comment ... which he quote tweeted to call the person a stooge for tagging Impact on Twitter.

We reached out to Mathews about all of this, but he wasn't able to comment.
