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

Good For One (GFO) 

“Good For One” is said with 100% absolute surety immediately after answering a trivia question that no one else in the team had a clue about.

“Good for one” is to be said with utmost pride, knowing that you (the most likely, if not, the weakest link in your team) just contributed one point and setting the “mic drop”/“my job is done here” benchmark. Don’t be shy about it - be proud!

Kudos to you, if your GFO was your ONE and ONLY contribution for the event, and actually helped win a middle position prize, or better still, moved your team off last and into second last place. Well done!

“GFO” can be used instead of saying/typing “I’m available for Trivia”. Very effective via an appropriate JPG/GIF. CAUTION: you are declaring that you will contribute and deliver at least one point for the Team. You may jeopardise your future with the team if you walk away with a “GFN” or “Good For None”. Understandably, no one wants to be that teammate.
“The answer is: Pine, red gum, iron bark. (I’m) Good for one!!!”

“I told you I was good for one tonight.”

“I’m booking a table, who’s in?” “Good for one (GFO).” (Yes, nodding JPG/GIF)
