|1.||Clutched my pearls|
To place your hand on your collar or around your neck in a prudish way as to display shock or disgust towards someone or something.
The imagery is that of a rich woman clutching her peal necklace in fear/shock.
That comedian was so vulgar that I clutched my pearls during the entire show.
Did you see that ugly baby!?!? ::say this as you clutch your pearls::
