There's really nothing too bad about it. I was worried my first year too but everyone ended up liking me. Thought I did throw pennies at freshmen this, AND last year.
Dude, we had this school thing (sorta it was over summer) it was like a dace, there was food and game shit.
In this big room, it was filled with 5th graders (soon to be 6th) so i decided to throw quarters at them. A couple cried. it was cool
