You breathe without thinking because your body does it for you automatically. But things can change your breathing pattern and make you feel short of breath, anxious, or ready to faint. When this happens, it’s called hyperventilation, or overbreathing.

That’s when you inhale much deeper and take much faster breaths than normal. This deep, quick breathing can change what’s in your blood. Normally, you breathe in oxygen and breathe out carbon dioxide. But when you hyperventilate, the carbon dioxide levels in your bloodstream drop too low. You’ll notice it right away because you’ll start to feel sick.
hyperventilating is not fun!

Hyperventilation is the physiological response to breathing to rapidly thus creating a surplus of toxins in the blood stream at a rate higher than the body cope with. Usually results in a passing out or fainting followed by a headache and sometimes nausea. Although most of the time minor it can and has killed people especially if done intentionally while also fighting the bodies natural responses.
Well I guess frank deserves to be dead for playing that stupid Hyperventilation game but somehow that cretin bastard has survived 20 rounds. I'm kinda tired of his stupid Hyperventilation shit that I hope he does die next time. I will laugh so hard I might hyperventilate myself hahahaha!!

Tony suffered from autoerotic hyperventilation every time he watched a Dua Lipa video. He hit his head pretty badly last time.

A condition where the rectum has a quite rational fear of being penetrated by a large member (again) and therefore has a reaction akin to a "panic attack"-causing the owner of said rectum to faint and therefore become incapable of participating in said sexual act-to the great relief of the rectum.
"Hey Baby-hows about some kinky butt sex"
"Sure Hun-lets go"
Anus...."Fuuuuuuckkkk....Noooooo.....Im still sore and slightly stretched from the last time..noooo..this causes physiological symptoms of "rectal hyperventilation" similiar to a panic attack where the "flight or flight"mechanism is hampered by the butts inability to send nerve messages to the legs to get the fuck away-instead it causes "Baby" to collapse in a faint in a public place making anal sex impossible or at least illegal!

Refers to what you do immediately following a super-stressful/worrisome period/event (like an emergency repair or tense/uncertain appointment with someone) which you have wheezingly struggled thtough without mishap (thankfully!); you are thus obliged to "deflate and regroup" in exhausted relief afterwards.
I was shaking in my shoes all during my 20-mile drive home due to some malfunctioning of my car's engine, but luckily I did make it back without incident, and then after I'd sat there in my driveway and de-hyperventilated for a few, I checked under da hood to ferret out da issues, and was immensely relieved to see dat it was all fairly-minor stuff dat I could fix myself.
