I would sit back and flick my boogers toward the front of the classroom and act half asleep when they hit someone.
This must be a joke. Where would you flick your boogers from?
I would do it almost every day sitting next to the window.
You shouldn't flick your boogers at people, because it is a very negative thing as far as society is concerned. It's gross and will not make you many friends overall if you're caught doing that sort of thing.
It's not like anyone caught me, nor will they because I know how to be stealthy.
Throwing boogers on people is unsanitary and people get riled up about things like this. If you want to keep your status with your classmates, then you need to consider stopping this bad habit.
