Taking a shit in a litter box.

Little Decker

When an adult takes a large dump in a little kids toilet and does not flush, so the small child's parents find it and believe it was jr. who did it. This will likely cause the child's parents to freak out and take their child to the ER as soon as possible after seeing the man-sized dump their 4 year old let loose.

What the hell?? Who left a Little Decker in my sons training toilet?

Starbucks Decker

Taking a dump in the upper part of the toilet at any Starbucks corporate or franchise restaraunt location (wi-fi not included).
