Any who sees a pool tattoo on you will take GREAT pleasure in beating you, so had better be able to back it up.
Years ago, when I used to play darts, I was waiting for my turn to play at a bar, and I was matched up with this guy who had a huge dartboard tattooed on his shoulder- my game was decent but not great, and I figured he was gonna kill me.
We were playing
cricket- he got ahead of me early and- instead of going for the win- kept banging me (unneccessarily) with points, just to show off a bit- only problem was that when he finally decided to end it, he couldn't buy a bulls-eye.
I started hitting a couple of bulls each turn while he continued to miss 'em- people were actually cheering for me (a rarity in darts in the US

)- I ended up erasing the point deficit and beating him, and he left the bar in embarrassment and disgust (he was without a doubt the better player- he just got cocky)- the tattoo made it all the sweeter- he had to live up to it, and didn't.
That happened over 15 years ago, and I still smile when I think about it.
