<span>This is a phrase by Bernard Shaw, Act 3 of Pygmalion.
He is describing how ill-natured sober men can be, and how their wives make them drunk in order to make them happy and to "make them fit to live with."</span>
Post hoc states that one event led to the following event that came after it. Since event B came after event A, event A caused event B.
This is fallacy because there are things such as coincidences, and an event coming after one doesn't mean they have to be related in any way.
