A true man is a person who can be a lazy bacon sandwich eating slob without caring what people think of them, it is only when you put yourself into a noodle/bacon/dr pepper induced coma in front of the TV that you reach true enlightenment. Jokes aside, I think that actually is more masculine than giving a shit about alpha male, getting huge muscles and being a stud etc, when did true men actually care what others thought of them?
On a bit more of a serious note, I think men that resist emotion are a lot less manly than those that get upset/passionate/romantic whenever the time is right, even if it is only when it is needed. I think the current stereotype of a manly man is terrible, and can't understand why anybody would want to be an emotionless hunk of meat having meaningless sex every now and again.
