1 gear is the term for someone who doesn't catch onto jokes quickly, or has no common sense.
This person that inhibits '1 gear' doesn't necessarily have a learning disability, they are just slow on catching on. They are completely aware of their intelligence but it takes them a couple seconds or a couple minutes to realize what is going on in a conversation.
Usually occurs when someone is trying to tell a joke and they don't get it. Or, when the person continues a conversation and the opposite person has no idea what their talking about after the conversation has continued.

When one accelrates in their automobile very slowly in first gear, until 4000 RPM's are reached, and the driver mashes the accelerator to the floor. If you drive a Saturn Sl2 or compatible, you will be glued to the seat and most likely have a mental orgasm. When the second gear is reached, the driver will once again crank down on the gas pedal until redline is reached. By now, you are most likely breaking the speed limit and need to calm the F down
My friend was braggin about his honda, so I gave him a 1st Gear Snap so he would shut the F up.
