Web-Jack

Someone who has to insult people on the internet for lack of nothing better to do. The difference between them and me is that to them, it's not a joke.

Webjacks can piss up a rope.

bag-jack 

To take the bag off a Volcano vaporizer before it's fully inflated, take a quick hit without turning off the air switch, and quickly put it back to be inflated fully for the person who requested it.

Ralf asked Florian to get Ralf high off a Volcano bag, but Florian was cool with it because he was able to bag-jack a monster hit for himself.
