BAGHDAD After more than eight years in Iraq, the departing American military's legacy includes a fledgling democracy, bitter memories of war, and for the nation's youth, rap music, tattoos and slang.

As the Dec. 31 deadline for completing their withdrawal approaches, U.S. troops are leaving behind the good, the bad and what "Lil Czar" Mohammed calls the "punky."

Sporting baggy soldiers' camouflage pants, high-top sneakers and a back-turned "N.Y." baseball cap, the chubby 22-year-old was showing off his break-dancing moves on a sunny afternoon in a Baghdad park. A $ sign was shaved into his closely cropped hair.

"While others might stop being rappers after the Americans leave, I will go on (rapping) till I reach N.Y.," said Mohammed, who teaches part-time at a primary school.

Eight million Iraqis - a quarter of the population - have been born since the U.S.-led invasion of 2003, and nearly half the country is under 19, according to Brett McGurk, a fellow at the Council on Foreign Relations in New York and, until recently, senior adviser to the U.S. Embassy in Baghdad.

So after years of watching U.S. soldiers on patrol, it's inevitable that hip-hop styles, tough-guy mannerisms and slangy English patter would catch on with young Iraqis.

Calling themselves "punky," or "hustlers," many are donning hoodie sweat shirts, listening to 50 Cent or Eminem and watching "Twilight" vampire movies. They eat hamburgers and pizza and do death-defying Rollerblade runs.

To many of their fellow Iraqis, the habits appear weird, if not downright offensive. But to the youths, it is a vital part of their pursuit of the American dream as they imagine it to be.

"I love the American soldiers," said Mohammed Adnan, 15, who pastes imitation tattoos on his arm. Adnan lives in Sadr City, the Baghdad base of followers of anti-American cleric Muqtada al-Sadr, who has threatened violence against U.S. troops if they stay beyond 2011.

But, surprisingly, Adnan says the U.S. gangster look is accepted in his neighborhood.

"All young men in Sadr City wear the same clothes when we hang around," he said. "Nobody minds. And we're invited to weddings or celebrations where we perform break-dancing."

Not all Iraqis welcome the culture the Americans brought. Dr. Fawzia A. al-Attia, a sociologist at Baghdad University, says one result is that young Iraqis now reject school uniforms, engage in forbidden love affairs and otherwise rebel against their elders.

"There was no strategy to contain this sudden openness," she said. "Teenagers, especially in poor areas where parents are of humble origin and humble education, started to adopt the negative aspects of the American society because they think that by imitating the Americans, they obtain a higher status in society."

As U.S. forces began closing their bases Iraqis rummaged through their garbage for discarded uniforms, caps and boots to sell to youngsters who pay top dollar to dress like soldiers. Baghdad's tattoo business is also booming.

Showbiz and military chic aside, young Iraqis agree that the American troops opened their minds to the outside world. The wait for a place in an English classes, for example, can last months.
