Well, I know this is going off topic a little here, BUT
lately anytime I here someone use the phrase "COME ON MAN!" to try and get their point across or "win" their argument, I automatically tune out.......
can't put my finger on the reason WHY
but there is just SOMETHING about the phrase "Come on man" that turns my attention to the speaker off.
It's really hard to take them seriously when they use phrases like "Come on man!"
