A spoken slang for BTW, meaning "by the way", which originated on the internet. Rather than say "bee-tee-double-u" out loud, people began saying "bee-tee-dubs", which became "btdubs" when translated back to the internet.

broken spoken version of instant messaging "btw" or "by the way". Instead of saying all of the "w", you shorten it by just saying "dub".
"I was talking to Kevin on the phone last night and BTdub, he says he misses you."

Pronounced "bee tee DUBS", a spoken form of the acronym btw which stands for "by the way."

It makes little sense, as the term itself has as many syllables as the phrase it's meant to abbreviate. Accordingly, it's degenerated into a cutesy term used mostly by girls. It has also been used in the gay community as a candid way of letting others know you are a bottom.
