Two Girls who have strange similarities And enjoy having picnics together. They often have similar shoe choices and enjoy eating vegan food together.
They have so many similarities they must be spirit sisters!

Get the Spirit sister mug.
Spirit sisters are two women who get along with each other REALLY good. Their chemistry is so good that they can not just be friends. They are more than friends but keep denying that they are dating.
Best example: Natasha Negovanlis and Elise Bauman

Interviewer: "You two are certainly more than friends."
Elise Baeman: "No, just friends. Spirit friends."
Natasha you-can-nego-my-vanlis-anytime: "Spirit sisters"

Its also used as a slang for two dating women but they want to keep it from other people (like fans).
