To bluff is to mislead by showing strength or confidence. People bluff to make themselves seem more powerful, larger, or of more authority than those being bluffed. A bluff is an act of bluffing. Example: The cabin was built along the bluff, but erosion is making it sink down the hill.

Etymology
Origin of bluff1
First recorded in 1620–30; origin uncertain; perhaps from Middle Low German blaff “smooth, even,” or from Middle Dutch blaf “broad, flat,” i.e., of a face or forehead
Origin of bluff2
First recorded in 1665–75; origin uncertain; perhaps from Low German bluffen “to bluster, frighten”; akin to Middle Dutch bluffen “to make a trick at cards”
Explanation
Bluff can mean a high cliff, or it can describe a person who is abrupt in manner. The most common usage of bluff is as a verb meaning to pretend. If you bluff at cards, you are pretending to have a better hand than you do. Many a good crime story ends with a bluff—"I've already contacted the police and they're on their way," the detective will say when that is not at all the case. The expression "calling your bluff" comes from poker, where you "call" a game to see someone's actual cards. Calling someone's bluff means forcing them to admit the truth.
