-The type of girl
Lil peep sings about in his song named Ghost Girl.
(It's either a female that you saw once or a few times, but never see her again, and
end up thinking about her the rest of your life.)
OR
(A girl you once were dating or had feelings for, but a guy, or multiple guys, take her
for granted, only to see her worth after they lost her.)
Example #1: I did everything I could to make him happy but I'm just another Ghost Girl.
Example #2: I saw this chick
jogging while getting my paper this morning, I think she could be my Ghost Girl.
Final Example:
I did her wrong and now it's too late man she's
a Ghost Girl.
