What is the longest time you have spent "fluthering" (in one sitting)

I don’t think I’m ever going to stop associating fluthering with farting, I think it must be because of fluffing.
Oh the the question, so far about 1.30 hours.

8 hours +

I have it up pretty much my entire shift on the reference desk which is six hours.

Like, 14+ hours when I was laid up in bed. I did other stuff but I was consistently fluthering.

12 hrs

probably like, 5–6 hours. I am on the computer a lot at night.
