The resulting misunderstanding that Jason Schwartzman and Jennifer Connelly procreated upon observation of a particularly thick uni-brow.

The observed browline is also referred to as an omni-brow. Because it can be discerned from all vantage points near or far, its presence is felt.
Dude: "Look at that omni-brow! Did Jason Schwartzman and Jeffifer Connelly have a kid?"

Dude 2: "Nah, thats just the genettabrow effect."
