Sleeping next to a woolly mammoth and you breath their exhalation! Amazingly sexy time that takes your breath away and your unable to sleep!
Jeremy quit being a woolly mammoth! Your exhaustigen is keeping me awake.

The other day at work I let out a bunch of exhaustigen from my ass and suffocated my co-workers. Hell yeah Jeremy! That's how you take care of the pot heads! Burned them to hell with your exhaustigen!
