When someone particularly lazy and/or fat is assigned a task in which they have decided is too hard. They solve the problem by lying on the ground and whining/moaning resembling a beached whale. OR when one or more lazy fat people watch a more fit, less lazy person do work.
Example 1: The Freshman P.E. class got the beached whale Syndrome when they were told to run the mile.

Example 2: I couldn't answer my phone because my boss got beached whale syndrome
