"I think I'll be irritated forever."
L.A. Dodgers pitcher Joe Kelly just RIPPED the Houston Astros ... calling the players "snitches" and "little bitches" over their cheating scandal in a scathing rant.
The reliever sounded off on his teammate Ross Stripling's "Big Swing Podcast" ... making the comments shortly after he was suspended 8 games for his role in a near Astros-Dodgers brawl last month.
Kelly explained to Stripling how he thought his ban was B.S. ... and then went absolutely IN on the Astros for the way he believes they passed off blame in their 2017 cheating scandal.
