Brisbane Lions tough nut Mitch Robinson did not mince his thoughts about premiership Tiger Tom Lynch during a live video game streaming session on Twitch.

Lynch has come under fire this week after being fined $2000 for striking charges during Monday's clash against the Gold Coast.

The star forward has also been maligned for an incident where he pretended to strike Sam Collins' face, only for the defender not to flinch.

It comes after Lynch escaped with a fine for pushing Lion Alex Witherden's face into the ground during their Round 10 clash.

And it's clearly left a bad taste in Robinson's mouth.

After a streamer commented that Lynch is the GOAT (Greatest Of All Time), Robinson replied: “Is he? Do you know him do you, f***head?”

Robinson added: “He went to a good team to get success, that’s what he did. He went to a premiership team and thinks he’s that good.

“He just does my head in. He’s a w***er.”

AFL 360 co-host Mark Robinson also took aim at the power forward on the Fox Sports program for his actions in Monday night's clash.

“If Tom Lynch was a mate of mine I would sit here right now and say, ‘Mate, you’re being a d****, what are you doing?’” Robinson said.

“‘If you don’t care what people think, no problem. But as a great mate of yours I’m telling you that everyone’s thinking you’re a d****bag for what you’re doing at the moment’.

“To go up and (feign) to hit Collins, that made him look like a fool. Why are you acting like this? Play hard, tough football, earn respect. At the moment he’s losing respect.

“He can live with that, that’s up to him. He’s a good person Tom but he’s just acting really badly on the field.”

Lynch departed the Suns at the end of 2018 to join the Tigers, winning a premiership in his first season at the club.

He booted 63 goals in 2019 and his tally this season currently sits at 19.
