When you get flashed so fast you only catch a peek of one boob before it's gone again. Then you finally see the other one and think, holy hell, those were laggy boobs.
My friend got flashed so quick, he thought he was seeing ghosts.
I blinked and missed the first boob. Then I blinked again and got the second one. Laggy boobs, for sure.
He flashed me three times and I still didn't get both boobs. Laggy boobs, baby.
