She most definitely is a narcissist. I think to be an influencer you sort of have to be. To want that much attention/be that self obsessed. Agree that professional athletes would think that’s hilarious, as you say she looks grand, perfectly normal. By no means an athlete, especially in person. She’s lucky she carries her fat on her bum/legs if she carried it round her middle instead she’d be in serious trouble.To be fair that is a tiktok trend where people use the same sound to show themselves going for a walk or whatever and say doing my stupid walk for my stupid mental health, so I wouldn't fault her on that as she's just joining in.
On the topic of her saying she's like a professional athlete or whatever, this makes me think she really is a narcissist. I've had my doubts in the past but she really REALLY didn't like being called out on it. I know she said it was just men but im not a man and plenty of others here aren't, and I thought it was a really awkward thing to say especially since she doesn't have the body of one (not being a dick she looks grand but let's be honest)
