How does our butthole know what kind of shit we have to take? We've all dropped the calm logs and also had experiences with the diaharea sweats, so how exactly does our binghole know the card before we play it? I've put a lot thought into this and here's what I came up with. At some point in our lives we have all entered a vehicle with the orange light on the console that turns off as soon as you sit on it signaling to both the driver and passenger, the airbags activated. You might wonder (if your a dimbass) how the vehicle knows your in the seat. It's not magic folks--it's science. When the appropriate weight is set upon the passenger side seat it sends the signal to the car computer. It basically says "we got us a motherfucker on the chair. Release the airbag safety so this waste of life doesn't smash his/her shit across the windshield in the event of an accident". Well, our heinie holes are a lot like that. When a well formed log crests the anal cavity it sends a message to your brain. "It's a log sir, no rush but if it's all the same to you we should pop this sucker out a s a p". But, when the diaharea his the anal wall-- it's more of a "gah fuck....the flood gates are going to go. This ass is gonna let it rip in t-minus 59 seconds whether it's hovered above a gas station toilet or not". In conclusion our asses are much like the weight sensors in vehicles. Thanks for your time and have a good night.
