A slut; one who is open for business, alternately, one with a fishy-smelling vagina and pungent stank.
Guy #1: "Man, I got with this total flapper last night..."
Guy #2: "Oh, yeah?"
Guy #1: "Yeah, I couldn't get the smell off of my fingers for several days."
Someone who talks shit & says things that they know & YOU know will never happen.
"If I knew it was your birthday I totally would have made you a cake or something"......whatever, don't make yourself LOOK like you MIGHT be a good person when your just a "FLAPPER"
