The true meaning can be found above ^ and therefor NO is the answer to your question
the modern meaning you are implying can be found here
http://www.urbandictionary.com/define.php?term=thug
it does mention that anyone can be a thug including a skater..
however, you will never be a thug, mainly because i know that you did not struggle, at some point in you life. and your mommy taking away your gameboy is not included as a struggle.
I am not speaking from experience because i have had it good my whole life...I am thankful, and I am not trying to degrade myself.
having said that, it is my personal opinion that no one in this country could be considered "thug," because no one in the USA has endured the suffering that occurs in less fortunate parts of the world.
