Kids between the ages of 16 through 24 who:
A) Walk around the aisles of Walmart late at night, giggling incessantly as they talk on their cellphones. They travel in packs.
B) Redneck kids who loiter in the parking lot with their car and truck doors open, laughing loudly and slapping each other on the back. These are evil people who are not only irritating, but they don't obey the parking spot lines. This can be late at night or during the day. Their population increases as the daylight decreases.

This can also apply to similar groups at other 24 hour locations like Walgreen's.

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.
