Boomnades

"HFB, hello fellow Boomnades" 
Boomnades are the evangelical and devout followers of KBism (also known as Boomnadism or Barryism) and worship the holy trollity of Lord KB (the son), his father Matt Bradley (aka God) and their namesake the holy Boomerang Grenade Barry (aka the holy spirit). They believe it is their duty to spread the holy words of the Lord KB wherever they go and to troll as many people as possible, as they are instructed to do so in their religious texts. A fair few members of the League of Mothers regard themselves as Boomnades, with the member Bradders as their ultimate lord. Due to their mischievous nature, many regard Boomnades as terrorists and KBism as a dangerous organisation as many argue it is not an acceptable religion in a civilized society, after all, we do live in a society... 
=== In D&D ===
In the LOM's D&D games, they were first introduced during the final session of the Tomb of Annihilation campaign set in the Velmaverse continuity, where during the iconic event known as the Destruction of Port Nyanzaru, many within the burning city of Port Nyanzaru, such as the Comrades, began to pray to the Lord KB to save them from the heated battle between Vladamira Torunn and a Balor destroying the city. With the final chanting of the phrase "WHYYYYYYYYYYYYYYYY", used to praise KB, a giant meteor fell from the sky and squashed the Balor under it, however in the process, destroyed the entire city of Port Nyanzaru. KB only saved those who he regarded as being worth saving, such as his loyal worshipers, known as Boomnades. Once the destruction was over and the dust had settled, KB's worshipers carved into the meteor that had landed and built a giant cathedral inside, naming it 'St Barry's Basilica'. This would become the headquarters of the KBism religion in this region of the world, regarded by many as a new world wonder. 
By the time of the epilogue session, Port Nyanzaru had been mostly rebuilt, now being called 'Port Nyanzaru Two: Electric Zookaloo', ruled by the gnome Czar Zook. However, the city was actually under the command of the Russian Lady, insisting the city keep to a communist way of life and forbidding any worship of a divine. This split the new city in half, with one side clutching with Czar Zook and his communist regime and the other siding with the Boomnades, This caused great tension within the city which culminated in a civil war...
