BTW:– BTW’s full form is by the way. By the way, we all use it, when having a conversation with someone. BTW Full Form… ”is an Internet slang where you want to change the topic of conversation or leave the current conversation and start with a new topic.

For example:-

In conversation:

Miley: Hi!
Ben: Hi, MILIY
Miley: Nothing, Just Chillin, What about you?
Ben: Plan to go to the GOA.
Miley: Okay. BTW! Did you read my book?
Ben: No, not now, I’ll read it tomorrow.
