Tybalt wants to fight Romeo... :)
Tybalt is associated with the Capulets, and he thinks of himself as a Capulet, but he is actually not a Capulet at all. He is the son of Lady Capulet's brother, and Lady Capulet is only a Capulet by marriage. That is why it is Lady Capulet, and not Lord Capulet, who is so furious with Romeo after he kills Tybalt.
Tybalt was upset at the party because Romeo arrived at the Capulet party. Tybalt believes that Romeo is mocking him and the Capulet name by arriving at the party. He attempts to fetch his rapier but his uncle, Lord Capulet stops Tybalt.
