As the title, states what's so bad about it? I see people here using that as insult, but isn't it a good thing to work hard? I'd say the opposite of a tryhard is the one that should be an insult. People just seem to use it here as a term for when they are annoyed at someone, but can't articulate correctly why so just resort to saying that.
If anything, hard work should be seen as a valued trait. .
