(n. pl.) - When speaking in public, you
experience a sudden
coughing fit - but you try to talk your way through it, leading
the audience to possibly hear something you didn't actually say.
Cough Derps in action:
What you said: "And so, you can see that *cough* 'is *choke* 's *hack* 'very *chork*"
What
you thought you said: "And so, you can see that this rare situation occurs in every byte."
What the audience heard: "And so, you can see that his rate of
masturbation is very high."
