They say the stink comes from the stomach.
And yes, we knew this kid, who not only had his breath stinking, but also refused to wash himself in the hot summer months when we went camping.
Then, nightfall came, we filled up a couple of buckets and a basin and we watered him down in his bed. We gpt punished for that, but still, we did him a good deed.
i drink a sip of listerine to make sure to neutralize and i bring the listerine bottle with me at the car so every lunch, i go to my parking space/car and wash it off. which is why my breath doesnt stink. kinda habit of mine. driven by paranoia.
oh man i never knew some beautiful women i met do have rotting carcass like smell.
i can tell you the full story but nah too much info.
