It gets on my nerves way more than it should when people call her a goth.

This is what google says:
Vanessa Doofenshmirtz
She is sarcastic, mild-mannered, cynical, and dresses in a goth style. Vanessa is aware that her father is an evil scientist and knows about her father's nemesis Perry the Platypus.

i prefer to call her "alt" style cause it means ur style can be mix of others style like emo and rock
