Express Yourself!

1.) "All Your Base Are Belong To Us"
The phrase "All Your Base Are Belong to Us" is from a Japanese video game called Zero Wing. It was a bad translation that turned into a joke among gamers. It now appears on many websites having nothing to do with video games.
This is mainly an 'online' idiom.  As the world becomes more global, mistakes in languages are often remembered because they are 'cute,' or funny.  My mother still asks me, "Where you go?' as a joke even though she knows very well, it should be: "Where have you been?" or "Where are you going?"
 
2.) Back Seat Driver
This idiom comes from the habit many people have of giving too much advice (unwanted advice) to the driver of a car from the backseat. This idiom means 'someone who watches and criticizes.'
 
3.) Close but no Cigar
If you come close to achieving success but reach a disappointment due to failure you are 'close but no cigar'. Many years ago slot machines gave out cigars as prizes. Also, early carnival games also gave out cigars as prizes.
