Funny because Sweetie Belle first appeared on G3 back in 2006.

Hilariously, I knew the meanings of those words and yet even I didnt think of that.

You obviously need to spend more time looking up rude words in the dictionary.
 
Like niggardly.

I have learned something on Derpibooru…  
What is this madness!?

Let us analyze. A faggot is a term for a bunch of sticks or twigs, while a bitch is the proper term for a female dog. I can only assume that 2006 represents the year. With this combination of wood and female dog, I can conclude that Sweetie Belle is roleplaying as a seven-year old female Timber Wolf. Sweetie Belle is just being creative in a manner that Rarity is failing to grasp. Therefore, Sweetie’s reaction of “omg sis u dont understand” is completely justified.
 
Now please excuse me while I take another swig of smart juice. My head isn’t quite fat enough.
