I personally dislike Wolfspeak, however because those who rp with me may find a very little amount of phrases that can be considered Wolfspeak in my own posts, I have nothing against those who enjoy and use these terms.
I was first introduced to Wolfspeak through a game called WolfQuest, which had a multiplayer version where a total of 5 players could come together in a server and do whatever they wanted, however roleplaying was the most popular. In the chat box, there was a chat that would replace a word that was spelt wrong, or a word you may have used in the post that wasn't apart of the game's dictionary with a ? after hitting enter, forcing the player to edit their post before it would be shown in the chat. This resulted in a lot of players having to turn to Wolfspeak, which was surprisingly apart of this dictionary. Now that I play FeralHeart however, that does not require this confusing and butchering language to be apart of the post, I really find it irritating.
Many people look at a post filled with Wolfspeak terms and have no clue nor could imagine what the words mean, and this causes a delaying within a Roleplay. Not to mention that most Wolfspeak terms have a definition that has no relation to the word the player is trying to replace the common term for, and is made up of butchered Latin, which ends up having no definition.
I know many who use Wolfspeak however find that it makes their posts creative, unique, which may be true. However no matter, I find it silly.
