The below is the part of conversation in the TV series, Modern Family:
Denise: He had a boom box and a piece of cardboard in his locker. And what was your dance name?
Haley's dad: O-Zone, Yeah
Denise: I drove him to his Star Search audition.
Haley's dad: Which is totally political, by the way.
Haley: O-Zone. That is dead-ass funny. I'm so calling you that.
Haley's dad: Thank you.
What does 'I'm so calling you that' mean? I know what call means such as in the usages, call his name, make a call, etc. But I totally cannot understand the calling in the sentence.
