Nothing but a sensationalist article based on bad science. If I may paraphrase the findings in simple terms: out of a narrow sample of 200 college-aged males, some guys were rated as slightly more obnoxious than average... those same guys said that they would like to have more hookups... and finally those same guys said that they do in fact have hookups.

Could it simply be that obnoxious guys like to brag about their supposed sexual conquests?
