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.

When you take a flash photo of someone while they are sleeping right before or after someone farted so they wake up to a fart sound and/or smell
She's giving you that look that Tony had on his face after I flash farted him and he yawn-gagged. It's like you're her nightmare in smell form.

A spontaneous and unscheduled meeting with way more people than need to be there. These meetings are generally unorganized.
