A serious talk between two close male friends, in which they talk about all the thingsgoing on in their life at the moment. Deep bro talks are sacred meetings, and all the things discussed during them cannot be told to anyone else without the other's consent.
Sam had a deep bro talk with David about his crush on Sammy.
A "deep talker" relates to an individual whom attempts to mask his feminine voice on a telephone or audio recording with hopes of sounding more masculine.
That guy is a deep talker, he doesn't sound like that in person at all!
My friend also tries to "deep talk" on the phone to fool the ladies into thinking he's cool and Manley.
