There's something going on with Ben Affleck and it looks like it's more than just his love for Tom Brady ...

The Boston-bred star appeared on the series premiere of Bill Simmons' Any Given Wednesday and went on a slurring, expletive-filled rant about the now-notorious "Deflategate" -- and it was just all sorts of uncomfortable to watch ...

We (and a lot of other people) are wondering if he had to pop some pills or take some shots before he went on the air, cause his cadence is all a mess?!

TMZ is reporting that the actor and Simmons got into a heated debate before cameras were rolling so that when they did begin filming, Batman was primed to go. And go he did ...

“Deflategate is the ultimate bulls--t f--king outrage of sports ever,” the 43-year-old said. “It’s so f--king stupid that I can’t believe it.”

For those of you who need a little refresher on "Deflategate" -- that's when Tom Brady was issued a four-game suspension for the 2016 season after an the NFL ruled that the quarterback was "at least generally aware" that Patriots staffers had deflated the team's footballs before their AFC Championship Game in January 2015.

The red-faced actor also took issue with the league's desire to for Brady's phone during the investigation (and the footballer's subsequent refusal to turn it over).

The Argo actor said, “I would never give an organization as leak prone as the NFL my f--king cellphone so you can just look through my emails and listen to my voice mails."

He added, “Maybe it’s just funny, lovely sex messages from his wife. Maybe Tom Brady is just so f--king classy and such a f--king gentleman that he doesn’t want people to know that he may have reflected on his real opinion of some of his coworkers.”

Umm we're damn sure that bad-boy Ben, who was rumored to have had an affair with his nanny, wouldn't want anyone seeing his texts!
