While not the only Joey-fronted song on K.G., it's hard to argue that this is not the fan-favorite of his contributions. “Intrasport” is a house song at the center of the album focused on bloodshed and transformation. While the title is striking, it is not an actual word. Instead, the title is a combination of intra (inside or within) and sport (competition, game). The title could then explain the song’s purpose: hunting your own kind or even yourself. Given the murderous lyrics, it makes a lot of sense. It was the last song from K.G. to be released as a single before they moved on to L.W. but it still holds a soft spot in many hearts.

Joey’s inspirations for “Intrasport” come from all over the place. For a Consequence of Sound explanation of K.G., he wrote that it was “my attempt at writing a Bollywood inspired, early 2000’s Housey-cum-RnB banger. It was definitely fun to experiment with the vibes found on this track. Britney… duet? 2021? It’d be a dream come true tbh.” In Gizzymail #7, Joey explained the song like this: “I think my idea for ‘Intrasport’ was a Turkish version of a 90s house song — It gets me one step closer to a duet with Darren Hayes from Savage Garden.” He would also cite Darren Hayes (alongside isolation) as an influence on the song during a November 2020 Reddit AMA. In that same AMA Joey said the gruesome lyrics were inspired by the dark web.
The COVID-19 pandemic largely influenced the creation of K.G., considering how everyone was recording and writing on their own and “Intrasport” was largely created by Joey himself (he has the sole mixing credit), while also being presented late into the album’s creation. Ambrose said: “‘Intrasport’ came about because Joey was at home and none of us were around him. He went free for all. He was listening to Savage Garden and guilty pleasures like that, although he wouldn’t call it a guilty pleasure. He wears that shit like a badge of honour. He also wrote ‘Minimum Brain Size’ which I absolutely love, but ‘Intrasport’ came late to the game. He’s done that a few times where he came late with a track and everyone’s like, ‘fuck’s sake, the album’s done’ and then he shows us the song and it’s really good. So then we cut one out and replace it with his. I remember hearing his ‘ah! ah!’ heavy breathing on ‘Intrasport’ and loving it, it’s really grown on me. It’s definitely the odd one out on the album.”
The creation process behind the song was detailed by Cavs in the previously mentioned Reddit AMA: “Joey had made the track with samples and then I drummed over the top. It's mostly Joey's editing and mixing that gives it a nice blend.. was very fun to play!” In the end only Stu (clavinet/synthesizer/Mellotron), Joey (vocals/guitar/synthesizer/Elektron Digitakt/percussion) and Cavs (drums) would play on the track, based on liner notes. “Intrasport” was released as part of K.G. on November 20th, 2020. Stu said that Joey was ecstatic about the track as it tapped into his long standing interest in electronic music. “Joe’s joke is that ‘Intrasport’ is his, like, government sanctioned electronic house track or whatever… Joe is pretty stoked about being able to take it to this place, for sure.”
