This woman is no 4-Genius.

A woman in Detroit was caught on camera going ballistic in a cell phone store when she wasn’t allowed to return her son’s phone, even though it was past the date that was allowed.

The woman got really worked up, trashed the store and even mooned the employee helping her (who recorded the incident) while saying, "Take my picture. Take that. Take that. You got that? Because I will be back. You got that close up? Cheese."

The woman claims the store sold her son an outdated phone. The store, meanwhile, plans to take legal action against her.
