Slamming is a special move introduced in Luigi's Mansion 3 that can be performed by both Luigi and Gooigi. To perform it, the player must pull on a ghost's tail until the suction gauge is filled up. Then the player can press A Button to slam the ghost in any direction that the player makes Luigi or Gooigi face. Every time a ghost is slammed, it will lose a chunk of its HP and drop some money. Additionally, any destructible object the player slams the ghost into will be destroyed and any ghost that the player slams another ghost into will lose a chunk of their HP.

A slam can also be performed on some objects if said objects have a Suction Shot stuck to them.
