An event in southern California when Hot chicks are supposed to flash their boobs on the roads and freeways.

Popularized by the radio station 97.1 Fm

Get the Flash Friday mug.
When you get on Craigslist and post a picture of a nude body part (boob or dick) under the personals section of causal encounters M4W or W4W and then get sent naked pictures back.
1. Can't wait to post my boob shot on Flash Friday on Craigslist and hopefully will get lots of boob shots back.

2. Can't wait to go under W4W and check out the Flash Friday pics on craigslist and maybe they won't mind a dic pic back.

3. Did you check out the Flash Friday pics on Craigslist this weekend? Wish they would stop posting ugly bodies.
