I have happened upon it in BBC Learning English. It is at 5 minute and 22 second. Here it goes:
[Bill] She is cheating!
[Will] So, you keep saying, but do you have any evidence?
[Bill] I literally just filmed it on my phone.
[Will] What are you doing! You could be blog-tubing the answer.
What is blog-tubing? I cannot find its definition on the internet.
