Sith are people who follow and embrace the Sith philosophy. That philosophy involves embracing one's emotions (positive and negative) to become powerful and, eventually, free one's self (physically and metaphorically). The Sith philosophy is centered around the Sith Code:
Peace is a lie, there is only passion.
Through passion, I gain strength.
Through strength, I gain power.
Through power, I gain victory.
Through victory, my chains are broken.
The Force shall free me.
By embracing the Sith philosophy, I have already become very powerful, and soon I will free myself from all bondage.
An extreme version of noob. Nub is to n00b what n00b is to noob or what noob is to newb. A nub might really suck at video games, be really stupid, or just be really noobish in general.

A door on the floor or ground, oftentimes in a castle, which can be lifted to reveal a tunnel or chamber. Sometimes concealed by being made to look like the floor, hidden under a rug, located in a secret room, or otherwise hidden so that it will only be found by those who know of its existence and location. Some trapdoors lead to a storm cellar for protection from tornadoes, but the more commonly thought of trapdoors are those from the middle ages. They were oftentimes entrances to dungeons where prisoners were kept, cellars where food and drinks were kept, or tunnel networks leading away from a castle that allowed castle residents to escape in the event of siege.
'Hey Liz, want to go explore that old castle with me? If we get lucky we might even find the rumored trapdoor! Then we can find the treasure in the dungeon underneath.' -Dylan
'Yeah, I'd love to! Can Josie come too?' -Liz
'Yes, of course, I was going to ask her!' -Dylan
'Awesome, this is going to be so fun! I love exploring secret trapdoors!' -Josie
