Spring Board 

A man who is about to receive a blow job in a dark room, tucks his erect penis in his thighs. When the woman goes down to look for the penis, the man released his erect penis from his thighs and it springs up thumping her in the face.

The spring board is one of the most effective ways to leave a mushroom stamp on your girlfriend.

String-board 

It is, apparently, some lost person's definition of the Shadow Caper's guitar.
The Shadow Caper and I were walking down the street after we had given a show to our hometown. And honest to whatever you believe in, this girl came up to us and said she liked our string-board. Read the example because that's honestly what happened. It was kind of stupid, but funny at the same time

Girl: "Hey! I dug the show you guys put on the other night. It rocked! I thought that you(*shadow caper*) rocked on the...string-board thing"
She could not get the word off her tounge. I'm pretty sure she meant"guitar"

Shadow Caper:"Guitar?"
Girl:"The what?"
Shadow Caper: You know, it has six strings and a lot of them have a hole in them"
Girl: "oh yeah"
