Similar to a normal titty fuck, the only difference being that the woman allows it to happen out of pity for the guy or the guy suggests it to keep him away from her nether regions.

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.
