User blog comment:Pary16/America also announced gay?? o.o (NOT OFFICIAL YET)/@comment-2241574-20100818171800

When translated to Korean, the word means "brightness, cheerfulness, gaiety" (ah Google, why are you so helpful and so useless at the same time?)

Roughly translated to English from Korean, the sentence apparently says: "A cowboy youth who is cheerful, has a friendly personality, and gives unreasonably big reactions." (apologies if this turns out to be false.)

Perhaps　ノリ in this case would mean リズム? (based on Watermint's link)
