Showing pleasure is a way of expressing joy and happiness. One way to show pleasure is to BEAM, which is to give off a bright light or to radiate joy. Another way is to GRIN, which is to SMILE broadly with the corners of the mouth turned up. Smiling is another way to show pleasure, which is to turn up the corners of the mouth and show teeth in a gesture of happiness. Wearing a SMILE is to have a facial expression that conveys joy and happiness. Breaking into a SMILE is to suddenly start smiling, usually due to being overwhelmed with joy.
