One version of it is
The State of relief and euphoia just after unleshing a giant crap(or perfoming "Shock and Awe") from your body... usually accompanied by a long sigh of relaxation as your sphincter retacts to its normal state. Much like the state of relaxation after an orgasm... kinda...
or version 2
