Mercutio is Romeo’s best friend. Mercutio likes to have a good laugh; he is loyal and is known to love wordplay. When Romeo is depressed because of his unrequited love for Rosaline, it is Mercutio that suggests they should all gate-crash the Capulet party. Which leads to Romeo first seeing Juliet. He can be easily aggravated and hates people who are pretentious or obsessed with the latest fashions.
