Its stupid and petty. By calling out an asshole this way you show yourself as also being an asshole. Resorting to passive aggressive name calling and insults from mild inconvenience is not a good look.

This isn't passive aggressive. Very much active insult.

Leaving a note and running away is passive. I see what you mean, but disagree.

I got a note like this once (minus the condom). When I had parked in the morning, there was an inch of snow on the ground so I could only park a reasonable distance from the person beside me. By afternoon, the snow had melted and the lines were visible. Sometimes people are just looking for a reason to be mad.

Free condom and I ruined a petty asshole's day? Score!

If the parking was obstructing something else you can report it to enforcement for towing/ticketing or the owners of the lot. If it was not obstructing something else then you are being ridiculous and trying to put people in their place. I read this reply as nothing but ego and lots of assumptions (shooting my brains out, wtf?)

If it's winter I'd stick it on with chewed bubblegum.

well, how bad did you park?

Better: leave a note so sorry for hitting their car, leave a number with most numerals illegible.

They will walk around it forever trying to see the damage.

I used to leave a flyer for a driving school that specialized in parking between two obvious parallel lines on asphalt.

The reason why these assholes park this way is because no one calls them out.

The sad thing is: you can pass shit on to others without being releated to them.

For mild evil, write down the number of someone you don't like
