An individual who bites their lip and trembles with ecstacy while using a sniper rifle in counter strike,plays the game 20 centimeters away from the screen,cringing everytime they die.Cringeworthy as f.
A person/people who simply try far too hard to fit in with you i.e. over the top laughing at jokes which arent particularly funny, name-dropping etc.

1: Someone trying hard to fit in with their crushes friends to get to their crush, only to dump all of his/her friends after achieving so.

1 Tryhard: Just because I talk to her friends, does not make me a tryhard!
Suspicious: Yeah, and is it such a coincidence you call out to your "friends" when she talks to them?
Tryhard: Shut up, you don't know anything! You just like to assume shit!
Suspicious: Oooh, looks like we have a salted ulcer!
2 Tryhard: HEY, WHAT THE FUCK!? I JUST FUCKING DIED.
Kid: Hahahahaha, I died again. :)
Tryhard: WHAT THE FUCK DID YOU JUST SAY, MAN?
Kid: What? I wasn't talking to you!
Tryhard: THEN WHY DID YOU SAY MY NAME!? ALSO, IF IT WASN'T FOR YOU AND YOUR NONSENSICAL BEHAVIOUR, I WOULDN'T HAVE DIED YA IDIOT.
Kid: Shut up, don't be so annoyed just because you died again.
*Tryhard left the game* (reason, to track down the kid and kill him)
Kid: Oh shit. MOMMY!
3: Tryhard: HEY GUYS, SORRY, BUT I HAVE SO MANY FRIENDS TO HANG OUT YOU WITH.
Kid number 1: I knew Sam was a tryhard, not only that, but he is as dumb as a rock, too.
Kid number 2: At least we have each other, right?
Kid number 3: Ooh Lala! Kids in love?
Kid numbers 1 and 2: OH SHUT UP.
This is not in reference to those that are scholastically ambitious, or put effort into sports. No, no. This is a strong, biting description of someone that obviously thinks a whole lot about their public image - fashion, vernacular, taste, etc. Such a person tends to fit very neatly into a particular pigeon hole - typically, a subculture. A tryhard is pathetically hyper-aware and irredeemably lame in their awareness and internalizing of all things external and obvious.
Pretty much the only phrase used is uttered snidely, under the breath to one's cohorts: "What a tryhard" or, alternately, "whatta tryhard". In particularly outstanding cases, "oh my God, whatta tryhard."
