The act of boasting/acting manly in front of a member of the opposite sex, in order to impress or woo them.
Did you see that guy nut-talking to the new girl? Man, I know he's never even seen a bull, let alone rode one.

Don't invite your friend over again. Last time all he did was get drunk and nut-talk at my little sister.
