Since I started playing online I've also noticed people using certain nicknames or just words to depict some monsters- for an example, most peopld shorten Deviljho with Joe or just Jo, but I always imagined him being more spanish, like Deviljh§.
Other nicknames I may have for monsters doesn't make as much sense;
Royal Ludroth - Ludor/Ludrotten
Slagtoth - Beagle (I swear they're just in disguise)
Ceadeus - Oden
Alatreon - Presley
Well. Those were my best ones. (And I didn't realize until now just how much Alatreon sounds like an effervescent tablet) --- I heard from a friend that I like to say "shut up!", but so what- I'm only reminding myself.
