Back Mouth 

When, during oral sex, the penis only reaches the back of the mouth & doesn't ever enter the throat. This could be due to the penis being too short or the girl refusing to take it deeper.

"She's terrible at blow jobs... She tried to give me head, but she refused to deep throat me, I got some 'back mouth' at best!"

I was fucking this chick in the Back Mouth the other day and she started convulsing. It looked like a toothless horse eating a carrot.

Back-mouth 

To talk back to someone while being a smart ass. Something an old fashoned grandma would say, along the lines of "Dont sass me"

Christian was very hateful on the phone with the nurse, so she yelled "Dont back-mouth me!" and hung up on him.

Step on a crack, break your mother's back 

This is an old children's game, anyone who trod on the cracks between the paving stones was out, until only one player was left, he or she was then declared the winner.

Step on a crack, break your mother's back– Most of us know the old rhyme “Step on a crack, break your mother’s back.” Whether the rhyme is the cause of, or a result of, this superstition is uncertain, though belief in it persists in many people today, even if subconsciously. Come to think of it, avoiding sidewalk cracks is probably a good policy for anyone who wants to avoid tripping.
