I take your point but this is what the Family Stand is for.
When the ref gave that "penalty" for Bournemouth I shot out of my seat and shouted "Ref, you're a kvnt!" Once I sat down I felt a bit bad, as I sit next to a lady in her late 60s. But then I thought about it and decided I had acted...
"Who's that kvnt Mr. Headmaster?
Who's that kvnt we all abhor?
No one knows his fvcking name
But we know the kvnt's to blame
Now my kids can't come here any more"
"Sacked in the morning, you're getting sacked in the morning, SACKED IN THE MORRRR-NING" etc...
