Have you ever growled at someone before? (Non-sexual)

Lol, I'm not a kyuubi, naruto, or anything along the lines.

Why growl? lol.

No, I haven't and don't growl.

i groan in a specific manor when i get irritated. my friend makes fun of me for it. when i get mad i talk in a serious tone, and get a little physically hostile. but i dont think i have ever growled before.

Umm NO i haven't Growled at someone
but i ROAR during the practice in the Karatedo Dojo
but now i already stop 2 years ago because the Dojo we use has been Rob
so they have to move..... now im stuck in Green belt how sad T_T

Ive growl every now and again at my friends if there starting to piss me off

Something to that effect anyway. I can't think of any specific times, but yeah.

I've never growled and is something like that even possible? it just seems to be too fake to be true. I can understand someone roaring cause they're high on roids but a growl at a paper cut or hitting your knee on something I just can't imagine that happening.

There are four people (to date) in this world who absolutely disgust me.
While confronting one of them, I growled.
He backed off, but it may be the death threat that followed.

I'm not gonna lie to you, I growl like this (below)
only without saying any coherent words

I don't growl, but in times of high stress I snarl at people who happen to say the wrong thing to me.
