You know when something's on the tip of your tongue and — as frustrating as it is — you'd prefer to try and think of it rather than look it up? There should be a word for that.
Looking it up just kinda feels like cheating, y'know? Or at least throwing in the towel.
Let me rephrase that: I never heard one. There is a word for tip of the tongue but not for the concrete situation OP described. I mean the possibility to just look up stuff wherever you are is a very recent development so it makes sense that a word that incorporates this isn't invented yet.
We're best friends now. Do another one: "when an Internet stranger connects with you over an infinitesimally small and unlikely shared idea or experience, and for the first time in your life, you don't feel alone on an earth with 7 billion humans, and you have a best friend"
