Fabolous

I hear 'em talkin' it

But ain't really livin' it

Opinions are like assholes

So who gives a sh*t

From the verse Fabolous contributed to "Start It Up," the 2010 Lloyd Banks single that also features a verse by Kanye West (as you learned -- if you were paying attention -- three weeks ago).  In The Dead Pool, which was the 5th and last "Dirty Harry" movie, Clint Eastwood says "Opinions are like assholes -- everybody has one."  The version of that line that I remember hearing years ago was "Opinions are like assholes -- everybody has one, and yours isn't any better than anyone else's."  A little crude, perhaps -- but it makes the point.
