A guy I served with just died and I laughed.
That's awful. Why would you laugh at someone's death?
He was a puss.
That is so rude to laugh at someone's death.  It is also bad to call him a puss.
Aw man you sound like a faggot. Just leave me alone.
I know it can be complicated to deal with a person's death but laughing or insulting him is not a healthy way to deal with death. You should talk to someone so that you can grieve properly.
