For me OIC is funny just for how pathetic he is, Shiro mentioned that OIC told him he was working out unprompted and sent him a picture of his water bottle in which he could see that he was fat because of his wrist (Shiro never asked for a photo OIC just send one to brag about how he is in the gym), he loves to roleplay as a gym chad and created a twitch profile with pictures of some dude that lifted. OIC didn't even know how push/pull/legs works as a split which exposed him even more when it comes to how he pretends to lift, you don't do push/pull/legs once a week.
The reality is that OIC is a lonely nigga that writes paragraphs about his life in Phil's chat (I'm quoting this down below), and the worst thing is that in those paragraphs he role plays as if he was starting a diet when he is fat, it's even more obvious because he said "The goal is to eliminate all carbohydrates and sugar to as close to zero as possible..." , nigga people who are actually fit don't have the problem of consuming so much sugar that it needs to be even thought about, people who are actually fit don't eat sugar at all or at most eat one small spoon of sugar with their coffee, if he needs to even think about reducing sugar it means he is eating garbage all day (hence why he had fat wrists as Shiro said).
OIC is a lonely autismo sperg that donates to Phil for attention and clearly knows what's wrong with himself, he knows that he is a fat lonely loser, maybe he works with computers and rather than doing whatever the fuck he is doing he would love to be a super hacker but he is too dented and lazy to do it, he knows he should work out but he is too lazy to work out consistently and also too lazy to eat healthy everyday (to the point he thinks "man I need to stop eating so much sugar"), he knows he should be with a woman rather than in Phil's chat but he is too much of a loser to get a qt wife so he just invented one, this lonely wheelchair role plays in a lolcow's chat pretending that he is living the life he wishes he had, and he needs to pay probably more than 1000$ a month for the privilege of doing this, fucking pathetic to pay a lolcow in order to escape into a world of fantasy.
