creased with laughter

1. Of the face, showing wrinkles because of hearty or prolonged laughter. My whole face was so creased with laughter by the end of Bob's hilarious story that it actually felt sore! I guess I missed a funny moment in the movie because, when I came back from the bathroom, everyone's faces were creased with laughter. I mean, if you're out with friends and your face isn't creased with laughter, are you even having a good time?

2. Of a person, seized with a laughing fit. Everyone in the audience was left creased with laughter from the comedian's jokes. Those two need to be separated—I can't have them creased with laughter in the middle of class. We were all creased with laughter during Uncle Phil's dramatic retelling of his bizarre trip to the market.
