repetitive sleep injury 

When you sleep in one awkward position so often you hurt yourself. Like a repetitive stress injury, but done in your sleep.

Jack- Man, my shoulder is killing me!
Amanda- Ouch, did you hurt it playing baseball?
Jack- No, I think it's a repetitive sleep injury.
Amanda- Stop sleeping on your side then!

scoreboard injury 

The act of faking an injury in an athletic competition in which your team is losing by a lot so you don't have to play anymore.

Dad: I'm sorry your basketball game turned out so bad. But did you see the way Mary collapsed in the middle of the floor? It was an Academy Award-winning slow motion fall. Eyes rolled up to the ceiling with a slow spin to the floor. No one touched her!
Daughter: I know. Scoreboard injury. She had to lay there for a while to make it look good.
Dad: Well, at least the other girls on the team who care about playing got playing time.
