back-break syndrome 

Back-break syndrome is when a girl ridiculously poses for a photo, putting her hand on her hip, sticking her ass out as far as possible, and bending her spine backward. Sometimes this pose accompanies a peace sign or duck face.

"Look at Gemma, she's posing for a photo like she has Back-break Syndrome. How ridiculous."

Back-up-break 

When someone stops at a red light next to an old person, slowly starts backing up, and yells "put on your brakes!" at them.

I can't wait for the day I get to back-up-break some unsuspecting old fart!
