Well, I'm certainly glad to be one of the "colonials" who doesn't consider paraffin to be kerosene! Nope! Not me! I'm one of the sharp ones who knows that it's actually a
type of wax. Etymology? I thought you'd never ask!! The name is derived from the Latin
parum (= "barely") and
affinis ("...suitable for use as fuel in an outboard").
Boy, good thing I'm here to represent.

I hope I've stopped someone from pulling up at a gas station and asking the attendant to fill up a jug with 5 gallons of wax. The ensuing hilarity would be entirely tongue-in-cheek, a distraction while a co-worker goes inside for a big old monkey wrench to straighten you out.
Also, "heating up a charley" is an unfortunate phrase from the Vietnam war and is not an advisable maritime activity! Particularly in this day and age, where such things are frowned upon in civilized nations, such as Transniestria, South Ossetia, Abkhazia, Nagorno-Karabkh and Mud Butte, South Dakota.
I understand that microwaving is perfectly acceptable...not to mention quicker.
Thank you.
