When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "WMDRock Library",
   title = "PI --- WMDRock Library{,} ",
   year = "2015",
   url = "\url{https://weaponofmusicaldefense.com/index.php?title=PI&oldid=800}",
   note = "[Online; accessed 16-November-2025]"
 }
