"shuck and jive": is a social activity that slaves (black employees) once participated in by large groups (before the advent of modern farm equipment used to "shuck" corn) to chat idly, gossip, or tell lies, spread rumors or (in rare cases) convey news or true, sincere feelings
Shuck and awe occurs while your gf or bf is giving you a blow job and moves down to toss your salad and finds a piece of corn still stuck to you crack.
my gf was giving me a bj and went to lick my butthole and found some corn. Unfortunately she got the shuck and awe and wasn't in the mood anymore.
