A group of friends went to the theater. The play was awful. Then, one of them says:
Did anybody else feel like they just wanted to peel the skin off their body, to have something else to do?
I know the translation of this phase but I could not understand its meaning. By the way, it was extracted from the scripts of Friends, episode 6, first season. The episode starts with a part of the play. After that, we have the first talk of some of the friends: "God. I feel violated.". So, comes the phase I marked above.
If possible, I would like some help to understand this sentence. Thanks in advance!
