I couldn't have said it better

Courtesy of Webster's, you know that book thingy with lots of words in it.

Whoopee interj. Slang. -Used to express jubilence. -make whoopee. To celebrate noisily ex.: made whoopee after prom

On a related note, I am clearly out of touch with contemporary English. I thought that I have been whoremongering all these years, but these days the kids are calling it whoremastering. I am so embarrassed right now.
