To try & sneak out a fart on the couch at your In Laws & then try & blame your toddler when caught out by the big stain on the back of your skirt.
Kaylene was on a new diet detoxing when she thought she could sneak out a fart. Unbeknownst to her, when she got up there was a stain on the couch. When her Father in Law pointed out the stain, she immediately tried to blame her toddler for spilling a drink. That is, until her Father in Law pointed out the big stain on the back of her skirt!!! So shitting your pants is now known as "Doing a Kaylene".
