1: When a piece of information, whether it be a fact, an idea, or even the knowledge of something's mere existence, slowly gets collectively forgotten about by everyone for no discernable reason. Aka, when some information figuratively leaks out of everyone's brains over time (temporal can refer to both the brain e.g. "temporal lobe", or to time e.g. "temporal anomaly").

2: When someone's brain (mainly the temporal lobe) literally disintegrates and leaks out of their head through their ears (where the temporal lobe is closest to).
Definition 1:
Timothy: Why does everyone keep forgetting I'm part of THE Edwards family? My last name is LITERALLY Edwards!
William: They can't help it. For some reason that piece of information is affected by Temporal Leakage.

Definition 2:
Timothy: WHAT THE FUCK IS HAPPENING TO HIM!?! WHAT'S LEAKING OUT OF HIS EARS!?!
Elizabeth: I think that's his BRAIN!?! *vomits*
Timothy: Is THIS what they mean by Temporal Leakage!?!?!
