Fupping

Smoking an electronic cigarette, another term for vaping. A description of the continuous puffing action used by E-cigarette users. Akin to the mindless constant chewing action of a Koala, and their stoned appearance.

I'm just going outside for a quick Fupp, anyone want to join me?.

Where is Dean? He's outside Fupping
