This is when a woman, is performing oral sex on a guy. She does not want the guy to 'nut' in his mouth. So the guy says, 'ok.'
At 'splurging' moment the man takes his hand pulls her head as far down on his 'knob' as he can, and twists...realeasing his magical man chowder as far down her throat as possible.

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.
