Flat Iron

A terrible istrument consisting of two hot metal plates. Used to burn and straighten teenage girls hair, by means of taking not pin-straight hair and pressing and holding it between aforementioned hot metal plates. A favorite among the the 13-18 year old age group. Occasionally used on sexually confused young men.
Can have awful results if you don't do it exactly right. For the teenage girl who thinks that curly hair is "OmiGod! Like sooo uncool!!!"

curly-haired girl : OMG!! Jessica, do you think all the cool kids will like me if I but this $80 flat iron???
Jessica: OMG!! Yes, because curly hair is so 90's!!
