I'm not a mountaineer, and I don't aspire to be one, but it's so cool to stand on a summit and see the world around me from places one can only get to on foot, with a lot of huffing and puffing and sweat along the way.

I sat stolidly puffing at my pipe and skipping over the pages of Henri Murger's Vie de Bohème.

Smoke was still puffing away.

Edmundo was puffing on a cigarette.

It's called "puffing," when drivers start their car and then leave it unattended while running.
