Someone who starts posing as an oddball or a weirdo once the stigma is gone and there's no social consequence. The kind of people who wouldn't smoke pot or do any drugs that would make them look like junkies until there was no stigma and everybody did it.
The oddball poser found a sense of comradery with a group of other oddball posers once there were no more odd people left, and phasing them out was complete.

Someone that thinks a team wants to be like another team because the other team has the better record. Nobody likes to lose, but would you rather lose as you or win as somebody else? It doesn't take any honor to win.
If you're not fighting as you, what's the point of being undefeated? People wouldn't allow their team to lose without a fight, but before they wouldn't let them lose, they wouldn't let them become a poser team. They would rather their team be losers or underachievers who were themselves than to be overachievers who were somebody else, even if it seemed stupid to everybody else.

The girl with the can of spinach tattooed on her arm would act like she was from the South Side of Chicago even though she wasn't even from Illinois and didn't live a day on Central time as a kid. She wanted to show people how much tougher she was than them, that was why she did all this poser stuff.
