hit the nail on the head with that one
The worst is what leads up to it though.
Your friend is about to do something and you think to your self how funny it would be to intervene with whatever theiyre doing and make them fuck up. You proceed to paint a picture of this situation in your head and it has a very pleasent outcome where everyone is laughing and thinking how funny and cool you were for doing that. You go forward with your plan but instead of a harmless joke you actually end up hurting or injuring your target. You then get that feeling in the pit of your stomach, the "i fucked up" feeling. No one is laughing or happy everyone is just quietly thinking to themselves how much of an asshole you are. Your face turns red and regret and embarresment sink in. (now insert what you said)
