How about some heavy nose breathing?
How about heavy nose breathing while eating? Have you ever sat next to someone that is chewing and breathing out their nose like they just ran up 7 flights of stairs? Yes, it is funny.
It’s like they’re just mad at their food. Take that, spaghetti! I’ll show you, ham sandwich!!
I imagine there to be a lot of noise clutter inside their heads. The sound of chewing and breathing loud would totally inhibit any thinking.
What’s that brain? I can’t hear you! Can you turn that down?? Quit your damn breathing like a horse! How many crunches can you get out of those chips? Sheesh!
