Backslash

That one annoying key that always gets pressed trying to hit enter or backspace.\

James: Hi!\
Andy: What's with that backslash?
James: Oh, I hit that stupid annoying key while trying to hit enter.\
James: OMG I DID IT AGAIN.
Andy: It's alright, everyone does it.\

Backsplattering

When you turn on your windscreen washer and some of the water sprays over the roof of your car and splatters on the windscreen of the vehicle behind, causing them to have to do the same thing. In a line of traffic this can result in a major domino effect.

Extra funny when there is a motorbike or cyclist behind you and they get wet and just have to suck it up and take it.

I was backsplattering in traffic and I totally backsplattered this dude on a bike, it was tooooo funny.
