Noun: A way of waking a sleeping person by spreading your ass cheeks while pressing your bottom up against the sleeping person's face and either farting really aggressively or defecating. The noise and smell this creates should be just as shocking and affective as the Nagasaki Atomic Bomb--the slumbering person will awake violently!
I gave Jimmy a Nagasaki Wake Up Call this morning to make sure he got up in time and didn't miss his flight.
