(Queer terminology, noun) A term used to describe someone who comes out as Queer while in a hetero-facing long-term partnership/marriage. Symbolic of spending a lot of life “underground”, going through a metamorphosis, and then emerging as the truest and most authentic self that glows in the dark and brings joy to others. Alternative to “late blooming lesbian”/“late bloomer”/“late in life lesbian,” but intended to be more inclusive of gender identities/expressions and sexuality representations.
“...Oh yeah, she’s a firefly, she left her marriage a few years ago and came out. Now she’s living her big queer life and is happier than ever!”

a brand of sweet tea vodka brewed in South Carolina. Tastes wonderful when made as an Arnold Palmer (Lemonade, Sweet tea vodka, and a splash of water) but taste like syrup when drank alone. This new vodka captivates preppy and southern charm in a glass.
Muffy and I sipped Firefly and had finger sandwiches in our sundresses and big hats at the horse races.
