Doubting Dragon

A phenomenon where someone believes they haven't taken a hit, because the draw was so smooth; resulting in the smoker performing the Doubting Dragon, where smoke billows from their nostrils and mouth whilst voicing these concerns.

*Takes massive hit*
Smoker: "Oh no, I didn't get anything!? Did it work??"
*Meanwhile, smoke is billowing out of their nostrils and mouth like a Doubting Dragon *
