CamelBacking 

The act of having a Camel-Bak or other similar hydration system that is filled with a hard liquor, usually vodka or everclear. Resulting in a drinking experience filled with ease and enjoyment.

Zach are you CamelBacking while we camp?
Of course, i love the simplicity of having liquid courage on me at all times.

Camelbacking 

The act of rehydrating by means of a backpack-mounted water bladder during a moment sexual intimacy.

She can go on forever! I would've lost at least two pounds of sweat and faced near dehydration had I not been camelbacking.

Comebacking

When you comeback from something, you are comebacking in a sense that involves magic and occasinally a llama.
But yeah, it means to comeback (in -ing form)

'2NE1, after not making music since the dinosaurs went extinct, is comebacking!'
