a person that you are comfortable enough with in which you are able to open up and look through their fridge without it being considered rude. Once this barrier is broken down, there will be no more awkward tensions within the friendship.
Dude, I'm so happy we're close enough to be Fridge Friends. Now I can just go through your fridge whenever I'm hungry without the awkward tensions. I feel I can really open up towards you now. Would you mind if I took my shirt off?
