The act of slacking and doing nothing all day, just like a lazy snake coiled up in its hole. Especially if you hide from view to avoid chores, work, etc. Also, any kind of total, undisturbed resting.
Sergeant: where is that lazy SOB? We have cleaning chores to do before the inspection!
Private: Uhh...he's probably snaking somewhere around here.
Dude 1: What have you been doing lately?
Dude 2: Uh....nothing. Just snaking all day.
I am so tired after eating, that I need a couple hours of snaking.
