A get-together held by really cool people with names like Sam and Sarah and Lunden and Frannie that is like a family reunion for people who aren't related. Lots of fun.
Sarah: Hey, Lundens going to be in town for the weekend. We should have a best friends party.
Sam: Great idea! Be sure to invite Frannie too. As many people should come as possible!
