It's used too much, and it get's obnoxious very easily
STRANGE FACEBOOK LANGUAGE:
Beeteedubs, btdubs, beeteedoubleu: It's orgin comes from BTW, which means By The Way. There is no reason as to why people say beeteedubs, it is less convienient, and it sounds stupid. It is also typically said in everyday speech. People think it sounds cool, when it only makes them seem more annoying then they probably are.
Ahhemmgee/Ohhemmgee: Originated from OMG which means Oh My God.
Many other terms are used. This is just a handful, these are probably the most common used.
