Aisle Salmon: The act of moving in the opposite direction of everyone else using the aisle. While they can be spotted in any type of aisle, they are frequently seen on airlines during loading and deplaning.
"Did you see the 'aisle salmon' trying to work his way back five rows to get a roller bag our of the overhead while everyone was trying to get off the plane?"
This is one of two things that annoy me more than they should on an airplane. How much time are you gaining? Three minutes? If you need that three minutes to catch your connection, go for it. But really, how often is that the case? My hunch is some people feel entitled to deplane with the row they sat in, regardless of where they stowed their bag.
The other thing I hate? When the person in front of me abruptly drops their seat back back. Yikes, that really lights me up. But then I think, "It's their seat, Dude. Lighten up. Yes, they do own the space up to just six inches from your nose. And, no, your laptop screen is not totally broken off. There are at least two wires and a bit of shiny tape holding it on."
