The coolest chick you will ever meet. She will take you on wild adventures that you never knew you wanted to go on. She will make your heart melt with all the joy she brings to peoples hearts. She has her friend's and family's back always and will never leave anyone behind. Just don't break a Marceline's heart or else it won't be pretty. People will try to bring a Marceline down but its only because they are jealous of how amazing she is. A Marceline will always know how to cheer up her friends the best way she knows how taking them on a adventure of wonder.

That Vampire chick from the show Adventure Time and is almost every 2010s queer kid gay awakening (if you were attracted to girls)
Marceline was one of my first gay signs as a kid. Without her I wouldn’t have gotten so into Adventure Time

the most precious girl to ever exist. She has the ability to make you smile even when she does the bare minimum. Anyone that has a marceline in their life is very lucky!!

A girl who is extremely sweet and nice and curvy and short and cares for everyone. Marcelines name came from her aunt who was born WAYYYYYY before adventure time.
