Same as "Talkin Shit" Putting a person down with the worst possible words you can think of. Whether they are true or not. It's all about makin them cry.
When people are about to fight they will be talkin as much trash as possible in order to get the other one to back down. It's also used in sports when 1 team will always be talkin trash on the other.
