Stands for GirlFriend Open (Relationship), the "R" is silent. The closest person in your life with the most wonderful personality. She's the type of person who makes you feel special and happy and brightens up your entire day. Every time you talk to her you feel like a fluffy, floating cloud and you can't imagine a life without her.

Since a relationship with a GFO is open, it is possible and entirely okay to have multiple GFOs. An important goal in a GFO relationship is to spread love to the world and expand the GFO army. GFOs are the future cure to the coronavirus. <3
