Oh definitley, but most of the time with men there will be some direct acknowledgement of the people they are shit talking. Like you can tell when two men don't like each other. 

  
With women, however, they will pretend to be best friends with whomever they don't like and shit talk.

Unfortunately I've been acquainted with several men over the past few years who  are very jovial to a person's face but really shitty about them behind their back. Whether it's men or women, I'd rather someone just be an asshole to me directly.
