KSI has revealed the origin story behind his name, says people are 'fuming' with him because of it

KSI has revealed the origin behind his YouTube name and explained why it left certain people “fuming” following his superstar success.

Fury stayed unbeaten as a professional boxer with the win, despite being docked a point for illegal shots to the back of his opposition’s head, while KSI (real name Olajide Olatunji) tasted defeat for the first time in a boxing ring.

According to KSI, the name originated from a Halo clan back in his Xbox 360 days and his desire to become a member of said clan.

As he explains in the above video, KSI revealed he was known as ‘KSI Olajidebt,’ which he initially also used on his YouTube brand before eventually dropping the ending.

Speaking on the origins of his name, he said: “KSI actually came from a Halo clan, so this Halo clan called ‘KSI.’

“I, as a kid, really wanted to join the clan, so my name was just Olajidebt on the Xbox 360.

“I remember going to this chat and being like, ‘Oh, I want to be part of the KSI clan.’ And they were like, ‘Ah, okay, you’re gonna have to change your name to KSI Olajidebt,’ blah, blah, blah.

“I said, ‘All right, cool, I’ve changed it, oh my God, am I part of the clan?’ And they were like, ‘Yeah, welcome.’

“And I’m like, ‘Yo, this is sick!’ And then eventually, obviously, the whole Halo phase went and I was just stuck with this name, so I kind of just kept the whole KSI part and just made it my own.

“And now it’s crazy because that clan is just fuming [laughs] because now they all look like fanboys of me.”
