A sad face tattoo is a symbol for tragedy. It is often paired with a happy face to depict the notion of laughing now and crying later.
The "laugh now, cry later" tattoo is popular among people who want a tattoo that sends the message that life should be lived to the fullest. The sad face represents the regret that comes from making a wrong choice. The sad face tattoo can be in the form of a mask that actors once used to convey emotion on stage. A tattoo of a clown with a sad face can display negative or hurtful emotions as well.
