I would normally never tell someone this because it's generally very unimportant... But, in this case I think it's probably warranted, so that you know for the future. The word "boof" [0] has come to mean something very different in recent times.
edit/ Read an article about the yearbook. I don't know how I missed that when all of that was going down. Thanks for pointing that out!
