Mega-tasking 

Performing 5 or more tasks at the same time. Mega-tasking should not be attempted if you are an idiot.

I was working on an excel spreadsheet, writing a word document, taking on the phone, checking my email, eating lunch and drinking a soda at the same time... I was mega-tasking.

Is when someone delegates multiple nested tasks ( tasks that themselves require multitasking) at one time, setting of multiple chain reactions of events, communication and assignments at one time. Ie multitasking multiple tasks at once.
