Ululate:
1. to howl, as a dog or a wolf; hoot, as an owl.
2. to utter howling sounds, as in shrill, wordless lamentation; wail.
3. to lament (or celebrate) loudly and shrilly.
The word ululate is new to me. The sound, however, is not. Arabic women are famous for this 'tongue trilling' cry that, if done properly, can friggin' shatter glass. I've heard it a few times over here, mostly on the TV news. Although, one of my male colleagues got really excited one day and let one rip right in class. Bridget also attended an Arabic wedding ceremony last weekend and she said that ladies were ululating into the microphone. She also said that one of her co-teachers sometimes ululates when a student gives a wrong answer in class. Awesome.
