Bone Flash

The instant where a man's penis become erect unprovoked. In other words, a random split second boner.

"I was sitting in class today and had a bone flash, it was so bad that I couldn't get up and walk around without being noticed. "

Or

Bob: "I just had a bone flash."
John: "WTF? Theres no girls in here."
Bob: "I know. Either its a bone flash or I'm gay."
-silence

Flash Friday

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.

Flash fart

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.
