2.
A moment shared by two or more individuals wherein a sudden mutual bond is shared around a possibly obscure meme. Often experienced when two folks from an online community meet by chance where each has a similar memetic reaction to the surroundings, conversation or scenario they find themselves in.
My instructor says in a faked sophisticated Mexican accent, "I don't always pass a student that rarely shows up." I quickly interupted, "but when I do, it's with a 'D-'." Suddenly, we realized we'd shared a mement.
