What's the meaning of the idiom "click one's heels". I can't seem to find it anywhere.
Here's some context:
Chloe: Clark Kent is a football player and Lana Lang is a waitress.

Pete: What's the matter with that?

Chloe: Nothing. I just wanna click my heels and get back to reality.

It's a reference to the movie "The Wizard of Oz," starring Judy Garland - can't remember the year, 1939 maybe. In the movie (which was based on a children's book by L. Frank Baum) Dorothy is carried by a tornado away from her home in the flat, dull Kansas farmlands into a wonderful, magical world peopled by little Munchkins and ruled by the Wizard of Oz, who lives in the Emerald City. The tornado sets down her house on the Wicked Witch of the East, killing her outright. Although Dorothy did not intend to kill the witch, she is hailed as a hero by the Munchkins of that area. Glinda, the Good Witch of the North, appears and tells that the witch's sparkling ruby slippers, which have appeared on Dorothy's feet, have magic powers and will protect her from harm. Dorothy wants to get back to Kansas, but is told that the only person who can tell her how to do that is the Wizard of Oz. She journeys to the Emerald City along a winding yellow brick road (another cultural reference from this movie: "Follow the yellow brick road!") with three companions: a scarecrow, a tin man, and a cowardly lion. All are seeking the wizard to ask him to grant their heart's desire. The wizard first sends them off to kill the Wicked Witch of the West (another cultural reference) which they do by accident when Dorothy throws a bucket of water on her and she melts away into a puddle. They go back to Oz to report their success. In their second interview with the wizard, he turns out to be nothing more than a little man, also from the heartland of America, whose hot air balloon crashed in Oz and who has been masquerading as a wizard ever since, using his skill to operate various enormous puppets, etc, in the throneroom of his castle. The companions inadvertently reveal him to be "nothing but a humbug" when Toto, Dorothy's little dog, pulls away the curtain behind which he is hiding. (And here we have yet another cultural reference: when he is exposed, the little man man frantically pulls levers and makes the enormous wizard head say, "Pay no attention to the man behind the curtain!") The wizard grants the scarecrow, the tin man, and the lion "brains," a heart, and courage, respectively, and promises to take Dorothy back to America with him in his balloon; but it takes off without her while she is chasing Toto. Then Glinda, the Good Witch of the North, appears to tell her that the ruby slippers will grant her wish; all she need to is click her heels together three times and repeat the words, "There's no place like home." She does so and, in the movie, wakes up back in her own bed; the whole Oz adventure has been nothing but a dream. (In the book, the experience is depicted as real.)

Here's the Wikipedia article, which has an even more detailed version of the story. I don't think I realized before I started typing how many American cultural references are from this film; I've omitted a few, too. Maybe you should watch it Emotion: smile

Hi,

To click one's heels means, as far as I know, "to wait" or "to wait for a long time"'

No. You are thinking of the idiom, 'To cool one's heels'.
