Tyrone McKenna and Regis Prograis ramped up the verbals ahead of their March 19 showdown.
Belfast banger McKenna is set to take on former world champion Prograis in Dubai in what is the biggest fight of his career so far.
It is a massive clash for the Lenadoon man as he looks to beat a man whose only defeat has come against undisputed super-lightweight king Josh Taylor.
McKenna is confident he can do a job on Prograis, while the American is convinced he is a level above the Belfast boxer.
The pair came together virtually in a head-to-head with iFLTV's Andy McCart, and sparks flew when McKenna was asked how he beats Prograis.
The Belfast man said: "I am hardly going to give away my game plan, am I? But look, I will (beat you).
"It's not rocket science. I've told you I am not going to box. I am going to stand there and I am going to go to war. I believe my work rate, my hunger, my b****, my heart, that's what's going to win me the fight."
Prograis has won 22 of his 26 fights by stoppage, highlighting the power of the Texan.
McKenna has just two defeats on his record, one coming against Jack Catterall who fights Scottish star Taylor later this month.
The answer promoted an immediate response from Prograis who countered: "You're really going to stand there with me? You're going to stand there with me? You see what I f****** do to people? I f****** lay people the f*** out.
"When I hit you I am going to f****** cave you the f*** in. This is going to be your worst f****** St Patrick's Day ever. I'm telling you this."
