One thing I really miss is hearing any chants from the stands like the one we used to do in HS when we thought a call went against us (which was most of the time). Chants like, "Elevator, elevator, we got the shaft".
Also, we'd yell when an opponent was going to shoot a FT, "See that basket, see that ball, c'mon stupid, hit the wall".
We never got reprimanded for any of it. Different times.
Oh yeah - some of us would yell in Latin, too.
