Hydroflask X M! Reader Oneshot

Y/N, the one male in his school with a hydroflask. Well, not JUST a hydro, but scrunchies, a fjalraven bag, and has gotten into the habit of saying the icnonic lines "sksksksks" and "and I oop".

During a particular day in his study hall class, the kids found out about his Hydroflask collection he carries in his Fjalraven bag. They bully him about it, throwing them around the room while the teacher is out and sending rude notes to him during class.

Y/N has had enough of their crud after two days of it, and decides to prove that his Hydroflask collection isn't completely useless.
