a flapster is a drunk mother, or woman over 40, who appears to be possibly a lesbian, but is not accustomed to sexual activity of the sort. it is impossible to see a "lone flapster" as they always come in pairs, or more.
Last night, my mom went to the neighbor's to hang out with her flapster friend. She came home a bit too tipsy.
The unholy union of Frat Guy + Hipster. A meathead in a dork's clothing- a phenomenon that is unfortunately growing all the more common as "underground" fashions push their way to the surface and into the mainstream.
I laughed for days when I saw a fripster run a stoplight get hit by car while riding his new fixed gear. Maybe he'll put a brake on it when he gets out of the hospital.
