...an adult throwing themselves a birthday party? Not cake & ice cream & a few friends & family, but "rented the banquet hall, DJ, having it catered, all-out birthday bash"?
My SIL is doing this. She's going to be 40, and she said that BIL won't throw her the kind of party she wants, so she's going to do it herself.
I had a very hard time keeping a straight face. I really wanted to ask if she planned on bursting out of a cake, too.
