A jack-off session followed by a nap; typically done right after a long day of work. A person engaged in a wack ‘n nap typically is so spent after ejaculation that they do not even have the energy to pull their pants back up before falling asleep. At this point a nap will commence and the participant often goes to sleep with their dick in their hand waking up some indeterminate of time later in a surprised state as there is still a mess to be cleaned up.
Man, this was the week that would never end. Before going out on Friday night I had a quick wack 'n nap to recharge my batteries before heading out for the night.
