When a man is having loving sexual intercourse with his partner, A treacy is when for some unexpected reason, the man sneezes whilst ejaculating and by a serious of unfortunate events, he unwillingly relaxs his anus muscle (the glorious sphinter muscle), and deficates on or around his partner, (soon to be Ex).
