An airplane passenger who immediately vacates their seat the moment the airplane pulls up to the gate and stops.
They quickly grab their bags from the overhead compartment and push forward, anxiously waiting in the aisle to deplane - like a rat abandoning a sinking ship - even though they still have 5 minutes before the doors open. They are usually talking loudly on their cell phones during this entire process.
Their laptop computers and carry on bags press into the faces of the seated passengers, who are oftentimes also treated to an unwanted ringside view of the aisle rat's rear end.
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?
Person who rudely ignores plane etiquite and pushes up the aisle past other passengers waiting in their row while plane is unloading. The correct etiquite is "unload the most forward row first, then the next most forward etc etc"

Aggressive or violent behavior exhibited by a shopper in an aisle, often as a manifestation of stress and frustration towards another shopper's ignorance. Walmart's equivalent of "road rage".
