Missing some context here. Is there response more of a legitimate "you're an asshole" or a "haha you're an asshole dude?" Regardless, you're just busting bulls. If they are legitmately offended, then they are probably easily butt hurt.
A couple that my wife and I are friends with make wall-hanging art pieces. When we found out we were pregnant, they made us a custom one. It was very nice -- very thoughtful. We did appreciate it.
However, the piece says that we're so grateful for what God "have gave" us.
Every time I see it, I poke at it, saying something like, "God sure do done did gaven her to us."
This usually evokes a response like, "You're such an asshole."
Is that an asshole thing to do, or is it innocent and harmless?
