Blowout - Definition 6 (slang) a lavish party or entertainment.
I know I talk a lot about wanting my own house, but I think it's something most of us who've not yet experienced it long for.
The day the papers are signed and the closing is complete, Auntie is having a blowout (probably several). I'm not waiting around for someone else to decide to throw me a housewarming party, I'm inviting over my friends and we're going to party like it's 1999. I'm going to meet my new neighbors and throw the neighborhood a barbeque. I'm talking jumpy castles for the kids and everything.
OK, maybe that's overkill, but you get the point.
I don't care if there's no furniture in my new house and the yard looks like an okra patch, I'm going to celebrate!
