To climb a rock face on the first attempt without any beta (previous information on how to complete the moves).

Rock Climber 1: Dude, that is so much harder than V8!
Rock Climber 2: Dude! I just flashed that shit baked out of my mind! There is no way that is above V5! You just spend too much time in the rock gym instead of actually climbing real rock!

In rock climbing, describes leading a route without falling after receiving information about the route beforehand or watching someone else climb it. See onsight and redpoint.

After my buddy told me how to surpass the crux of the route, I was able to flash it with ease.

Bob: Here, I'll guide you through it. First grab the bottom of your shirt...
