yes, it is commonly used in daily life

就是Something becomes very clear all of a sudden.  That is, all of a sudden you can understand something you have doubted. Take Palmolive soap as an example.  One day I looked at the bottle of the Palmolive soup and I was like “oh,  I have the epiphany  that the Palmolive soup is made of palm and olive.”   诸如此类的情景都可以用得上。
