A feeling you get during a Fortnite solo match, when it's come down to the top 2 players: you, and your opponent. While searching for or fighting your opponent, your hands begin to shake, your heart starts to beat faster, and possibly breathe heavily. Usually, you shouldn't panic during a 1v1, but it gets to you easily. Once you get that feeling, the only way to stop the attack is to finish the game, either you fire your shots accurately, or you take the L like a man.
No matter what, everytime I'm in a top 2 situation, I have a 1v1 Panic Attack.
