An event or mistake that is so disastrous that 'fuck-up' isn't strong enough,so 'fuckfall' is substituted,as this shitty happening in your life is equivalent to a long fall down a well or off a rocky slope.

A pick me is a woman that is willing to do anything for male approval. She will embarrass or throw other women under the bus to achieve this goal. The unfortunate thing about a pick me is usually the men they are trying to seek approval from are of poor quality and treat women badly, leaving little real benefit for the pick me.
