Swantaneous 

when someone does something spontaneous that has a hilarious out come. It normally occurs on a whim, drinking may be a contributing factor.

(after a few drinks) "I am feeling swantaneous tonight, lets take winston for a drive."

Spontaneous Research Call

A Spontaneous Research Call, SRC is a prank call placed to a business in order to research how ridiculously far companies will go to please their customers for more business. Such calls may also be made to international embassies and the like, to confirm or deny media reports. They are often prompted by a crazy tabloid news story in popular culture.

Spontaneous Research Calls have been coined and popularized by The Sir Darryl Radio Experience , the most listened to radio program on the internet.

Sir Darryl will call companies and it reveals the absurdity of our corporate and customer service culture that will say yes to anyone who offers money, notoriety or other compensation. Sometimes, the company's spin machine is at work. At other times, these calls expose the genuine professionalism and helpfulness of the representative. Sir Darryl calls funeral homes, landlords, pharmacies and the like, with unusual requests. The responses from the company reps are either completely insane or absolutely logical, but they almost always follow company policy.

In one Spontaneous Research Call, Sir Darryl called a cellphone company to find out if they could send him a separate phone bill that his wife couldn’t see so that he could hide the fact that he was having multiple affairs. The customer service rep suggested different billing options and promising that the company would not reveal anything to his wife. The rep also detailed exactly how it could be done using the company’s various billing delivery systems.

spontaneous bidet 

Incident in which you take a dump, and the toilet splashes you back in perineum. This is different from a regular bidet in that it's the toilet water that's splashing you, not a directed tap.
As a rule, this nearly never happens at home, and it frequently happens when you're forced to use a stall with overtly nasty waters or after you've already urinated.

person one: I'm a little worried. I had to use the portajohn at the airshow, and it gave me a spontaneous bidet.

Friend: Dude, you need to see your doctor.

Spontaneous shitting 

When you have a big juicy Five Guys cheeseburger and 45 minutes later you shit yourself in the most embarrassing situation. This usually happens when the burger is made with jalapeños and hot sauce.

Last night I was hanging with Carol, and just about as I was ready to stick it in, I had a spontaneous shitting. It was all over he place. She laughed.
