This is causing a big outrage on Social Media.

They get em pissed young up in Jockland don't they.

Sometimes I find it hard to side with the Celtic fans. It’s not easy being pro British and supporting the Bhoys!!

I’m sure Sean will have a more detailed view as he is a genuine fan and not just a fair weather one like me.

Unfortunately these sort of people are on both sides it comes from the parents and will never go away. It doesn’t matter what team you support you should always Show a bit of respect to others  and have some dignity unfortunately even some on here lack this 
Stupid little boy.
