When you're desperately needed because of an unfolding catastrophe, but you skip out to go somewhere less stressful.
Them: We have a project due tomorrow, the boss shouting at me, and the clients have been calling nonstop for the last two hours! Where the hell is John!?

The act of leaving behind friends, family, coworkers, cohorts, etc. when the current situation gets tough for a leisure vacation. Preferably somewhere tropical.
