How do you define the word "gentleman"?

He should be the man who makes his girl's heart beat faster. with a fast beating heart she could open her door, pay for restaurants, clean things and be ready to go even to the most boring place.

It's simply how u treat her with dignity.

Holding doors, carrying her stuff is just the basic,

Gentleman = A man who treats both males and females equally

Well, living in the south; I imagine a gentleman is someone who owns a large cotton plantation and more than 50 slaves. He has an aristocratic southern accent that sounds like an ultra affected English aristocratic accent but with the southern lilt added. He is well mannered and hospitable, good at horse riding, sword fighting, and hunting. He is highly educated, well read in the classics, and is involved in government, civil service, or the military always in a leadership position of thee fields. He throws lavish parties and spends generously on his guests at these parties. He holds to a code of chivalry brought from the days of his European ancestors that involves both the modern meaning of dealing with women and the older definition regarding martial spirit and honor. He has a huge sense of honor and his own reputation which when the latter is besmirched he responds the offender by challenging him to a to a duel if he of equal social standing. He is extremely conservative in the old European sense of believing in natural hierarchical order of aristocrats, peasants, and slaves. His religion is of Episcopalian faith as that is a gentleman's religion. A gentleman believes that sins of the flesh can be forgiven and thus is prone to smoke tobacco or drink bourbon. He is racist believing black people are inferior and are in their natural state as slaves. But you probably meant something else by your question so...

In the Antebellum period of the south, the true aristocrats in that society were people with over 50 slaves. But I don't own any though. Abraham Lincoln said we can't anymore  . However my grandmother swears that in the 1940's her family owned slaves so... I guess we didn't listen.
