It's a unique kind of relationship, or at least a new term becoming a part of the pop culture lexicon, and was even the subject of the 2009 comedy "I Love You, Man."

According to a new study conducted by Badoo, a social networking site for meeting new people, "nearly three out of four American men either currently have a bromance—a close platonic relationship with someone of the same sex—or have had one in the past."

And of the 4,000 study respondents, Badoo found that "60 percent of men in the U.S. say their relationship with their BFF causes problems with other people in their life" and that "16 percent of partners–girlfriends or wives–admit they’re jealous of their beau’s bromance."
