What it is
Mugging is stalking with a pole. You watch a fish, ship a short shallow rig out in front of its path, and lower a bait — often a bit of bread, corn or a pellet — so it intercepts it. If you throw feed, you are doing a different method.
It is not a default. It is for days when they are cruising and ignoring a bed. Heatwave welfare still applies: land them, keep them wet, do not play them to exhaustion for a photo.
