way of speaking; manner of talking
Refers to a person's characteristic way of speaking, often implying glibness or a smooth tongue. Can also refer to one's profession or trade, especially in contexts like 口前がいい (to have a smooth tongue) or 口前で食う (to make a living by one's wits or eloquence).
He has a smooth way of speaking, so he's suited for sales.
I'm always impressed by that person's way of talking.
Compound of 口 (mouth, speech) and 前 (front, before). The exact historical derivation is uncertain, but it likely developed from the idea of what comes out of one's mouth or how one presents oneself verbally.
