What does it mean when people say something in a cough?

this is probably a stupid question ^_^;;. what does it mean when people say stuff in a cough, like idiot and stuff? there was this really jerky girl at school who used to always do that and i just gave her a wtf face and walked off, but i never knew what it meant. i feel so stupid... but the girl got expelled about a month before summer break so i guess it wasnt just me. i heard she gave a girl amnesia by hitting her too hard on the head... im glad im taking tae-kwon-do again lolWhat does it mean when people say something in a cough?
It's simply to give the pretense of saying something without you hearing it, where in reality you really are meant to hear it.

Example:

"(coughing) Idiot."

"What did you say?

"Huh? Oh, nothing, I just coughed."



It's usually used in a teasing manner, as far as I can tell.What does it mean when people say something in a cough?
That they never grew up or theyre trying to be a comedian.. But most importantly they dont have the balls to be honest and say it to your face.{ Definately not gonna play with your hampster anymore! }People like that are best to be avoided,k?What does it mean when people say something in a cough?
It denotes sarcasm at times, albeit however it's meant to be said. It's mostly used by young ones who have a bad attitude. It's really impolite.
Wen they want 2 b rude or sarcastic they say it like its innocent but they want u 2 hear it jus 2 get on ur nevers
