If you look closely at the Wikipedia article, you'd see that the text in the infobox is 五毛党 (五 wǔ 5, 毛 máo 0.1 piece, 党 dǎng political group [No relation to Daniel G]).
What you wrote is 50 美分 (měi fēn American cent) 派对 (pài duì fun get-together.)
I get Bing results for both, but the "American cent" ones are all about the rapper.
