I wish people wouldn't do the 'laugh emoji' or try to take the piss when somebody shares a pic of their tattoo.
It's pretty dickish behaviour. It will obviously upset the person who has chosen to share.
I'm guessing it probably means a lot to them, so don't try and pick fault or laugh.
For the record, I don't have a tattoo, but if I did, it would be of Jimmy Willis on my little Jimmy Willy.
