The word "Flail" can have many meanings. In todays culture its mainly used to descride the way teens or young adults act in public after about 3AM. i dont know if the dark has an effect on their not fully matured minds? i believe its because they feel as though they have super powers after 3-4am. the youngsters 'Flailing' become insanly witty and use their mind to humiliate themselves and the others around them. Including strangers that happen to be going about their lives and randomly run into a group of 'Flailers'. The 'Flailing' youth really show their true potential during this event. It allows them to seperate from one-another and be independant while seeing who can think of the most ridiculous antics to pull. This act is normally after the 'Flailers' have tangoed with a drug called Crystal meth so their brains are running at full capacity. It also influences their actions in a hilarious, smart assy type of way. Which makes for a evening thats unforgetable!..but already forgot at the same time.
(from one flailer to another) "yo you wanna role over to walmart and flail like a motha fucka?"

"I wish i would have thought of that!" - Fellow Flailer
