Tryhard

Tryhards are people who make too large of an effort at something and inevitably end up crashing and burning. It's typically to make themselves look better than they actually are so no one will know they're just lowly morons.

There are many defining points of the tryhard with the main one being, of course, that they try too hard and suck at everything. If you're going tryhard hunting sometime soon, it's useful to keep these following notes in mind:

You've found a tryhard if the person...
 * Excessively does something they believe counts towards being something else, like swearing to look cool or tough.
 * Looks lulzy or just plain stupid when they do things.
 * Is called out by the people they're trying to be.
