Kingdom-Hopping
From AmtWiki
The practice of an amtgard chapter switching kingdoms on a regular basis for any number of inappropriate reasons, such as personal grudges, desire for more awards (even knighthood), or even whether a given weapon is allowed.
This can happen anywhere, but has been particularly a problem in the pacific northwest, where the Kingdom of the Mystic Seas and the Kingdom of the Valley of Silver Rains both exist in the same area.
Kingdom-Hopping as mentioned is an entire chapter switching kingdoms, even it if it motivated by just an individual. If an individual swaps park, that is termed Park-Hopping.
