Jin Young Park's new music video for "Who's Your Mama?" has become a hot topic online, reaching more than 4 million views on YouTube in just 6 days.

Based on the YouTube comments, fans had been watching and liking the video because of its hilarious scenario where Jin Young Park (who often goes by his initials JYP) goes on to ogle the beautiful women in the gym, especially their nice butts.

Aside from the fun factor, fans also had good things to say about the cheeky lyrics, catchy beat and the appearance of featured rapper Jessi who looked sexy in the video.

Helped by a hit video, "Who's Your Mama" has ranked first in several music charts, a fact that he was a bit remorseful for as it took the spotlight away from the comeback of miss A, a girl group under JYP Entertainment in which Park Jin Young is the CEO.

"I don't care what anyone says. This is my Jam! My girlies and I dance to this all the time. You go JYP! Shake that Bootay," said enthusiastic YouTube user Sid-Sic (이 시드니).

But the song has its fair share of detractors. Criticisms have focused on what they claim to be depictions of sexual harassment and objectification of women.

"All I got from the MV and English translation is JYP is a sleezebag who checks out girls at the gym and he has unrealistic body expectations for Korean women aka 'thin waist and big booty that make it hard to find pants'" said YouTube user alex tran.
