Hey, ref, you missed a call
This woman found a pretty creative way to let the referee know he’s missed a call! While some fans go with the old, cliche slogans, others see this as an opportunity to unleash their creativity. This seems like a positive way to let out your anger; it’s surely better than screaming curses at the referee.
And clearly, she’s made an effort to prepare this sign, which you must give her credit for. However, I’m not sure the people behind her, who have their view blocked by this giant sign, would agree with us.
