The Casa Amor stud won his place in the main villa after striking up a potential romance with Billykiss Azeez, who brought him back with her.
However, now he's moved on with fellow Casa bombshell Emma Munro – with the pair even sneaking off to the Hideaway for some private time and a snog in the pool.
He also officially broke things off with Billykiss, with the pair deciding the spark wasn't quite there for either of them.
The move came as a shock to fans, who didn't understand why they suddenly cooled off, although they'd noticed they had not appeared on screen as much over the last couple of days.
But fans have become convinced that Boris deliberately used Billykiss to get into the villa, using his charm on her only to ditch her once he had secured his spot.
Branding him "horrid", viewers have said that he should be on the "next plane home" as they vented on X (formerly Twitter) and Reddit.
"Boris used Billykiss. I was never falling for that propaganda. Get him out. #LoveIsland" wrote one.
"Boris wym finally… imma make sure ur ass is on the first flight back to Slovenia," said another.
"Send both boris and emma home,they made it easy for the viewers #LoveIsland" noted a third.
"Boris literally pretended to like Billykiss. Horrid," noted a fourth, while a fifth said: "Boris playedddd Billykiss to get into the villa icl [I can't lie] #loveisland"
To further add to the awkwardness of the situation, Billykiss and Boris are still technically coupled up, with Billykiss being left with no choice but to choose him in one of the most awkward recoupling ceremonies ever.
But things are set to get even more dramatic with surprise dumping set to take place tonight, with a major player being axed from the show.
A source said: “The way this dumping played out was truly savage. It was absolutely shocking.
“This Islander has been integral to the series - they’ll be talked about for years - and so to lose them was a massive moment for bosses and will be the same for viewers.
“The scenes will play out over the next few episodes.”
Love Island continues tonight at 9pm on ITV2.
