A word commonly used for children who's sacks have not dropped. They usually have a very high pitch sqeaky asian voice and smell. Commons wee rabs known to the runescape world are Coconutdonut, G warrior94, pkerdude30 (stevie28) and pkingpure007. If you ever meet one of these wee rabs in real life you are entiteled to smack then in the nose for being the most annoying wee rabs in the world.
Oh yeah they also have no pubes, tiny penises and cannot even produce sperm.
Pkerdude30 was pissing me off so I called him a wee rab and popped his asian nose.
