The humor behind this movie can only be described as a female version of hangover... However, NO IMITATION whatsoever completely original and great for dudes to watch as well... This isn't the typical chick flick my friends... like a little blonde said when entering the movie, "OH! It's rated R, that means it's going to be funny!" LOLZ enjoy!! p.s. I recommend not watching with elders who have role model status i.e. parents and grandparents... or your 22 year old children... kind of uncomfortable :D
