"Engagement" in a social media context. Most of the time, I'm not engaging with anything, really. You wouldn't say you're engaging with your newspaper when you're reading it, or engaging with your TV by changing the channel. It's ridiculous
At the same time they're saying "I'm not a try hard. I could beat them any time I want but I choose not to". GTFOH loser"Nerd" is used similarly for kids who do well in school.
Unsurprisingly
