Nessi is the cutest nickname for Vanessa on this entire planet. Is actually just as awesome as a Vanessa, but a little bit kinkier and more depressed. The only thing she reads are gay fanfics with a lot of smut. She is extremely sensitive, so watch your mouth! She is the perfect combination of cute and hot af. A lot of guys want her, but she only wants that one person. Literally the most supportive friend you'll have and also the chillest roomate. If you have a Nessi in your life, show her a lot of love and affection and let her know that she is a very important human being, that lights up your world. (because that's what she is)
