KSI was the winner of a recent boxing match with YouTube rival Joe Weller, as the two faced off in front of a crowd of 8,000 and a web audience of over 20 million on Saturday night.
In his victory speech, KSI had a few choice words for disgraced YouTuber Logan Paul and his brother Jake.
"If any YouTuber wants it they can come and get it. Jake Paul, Logan Paul, any of the Pauls - I don't care. Bring it," he said.
Looks like Jake Paul heard the call-out - today he responded via Twitter, but attempted a put-down that didn't quite land.
"Who is PSI and why are people tweeting me about him?" he wrote, presumably attempting a weight-based jibe by referring to 'pounds per square inch'.
KSI's response was simple and to the point. "Boy, I would drop you quicker than Disney," he tweeted, with a nod to the 20-year-old's cancelled role on Disney Channel series Bizaardvark. He also posted a screengrab of Paul's Twitter profile, which reads "I have fun, eat food and Team 10 Instagram: JakePaul".
It's been a tough few weeks for Jake Paul, whose brother Logan recently withdrew from the public eye following a controversial video which featured a dead body in Japan's infamous 'suicide forest'. Earlier this week, a video of Jake rapping also surfaced, which has attracted criticism for his use of 'racist' language.
Logan Paul has yet to respond to the challenge.
KSI and Weller's bout at the Copper Box Arena in Queen Elizabeth Olympic Park, London, was the culmination of a drawn-out feud which has seen the pair fling insults such as'stupid' and 'moron' at each other.
It began when Weller accused KSI of faking a fight with Sidemen members as a publicity stunt, before KSI released a diss track about Weller. Weller then responded by calling KSI a 'melt'.

The fight was originally scheduled for six rounds of three minutes, but was cut short when the referee intervened when Weller began to look worse for wear during the third round.
"I walked the walk, and I talked the talk, motherfucker," bragged KSI as he celebrated his victory.
However, he found time to praise Weller, adding: "Joe, you're way tougher than I thought. Respect for getting into the ring and giving me a tough battle."
