Padded shorts used for biking, also known as a chamois. Feels like a full wet diaper when you sit down after a long bike ride, but instead of urine, it's wet with crotch sweat.
Person 1: "good ride, man."
Person 2: "Yah, that was a long one. I really need to go change my biker diaper."
Person 1: "gross.... Me too...."

The act of defecating in the baby changing station at a public bathroom, then folding up the door leaving a nasty surprise for the next parent. This act comes from the idea of an "upper decker" or a "top shelf".
The toilets in that rest stop are disgusting. I couldn't take a chance to rest my cheeks on one of those seats. So I left the men's room a diaper decker.

When a female's full covering bikini tan lines leave her buttocks ghostly white while her legs, stomach, and back are beautifully tan leaving her to look like she is wearing a diaper while in the nude.
A Diaper Tan is when a girl is fully nude and her body while beautifully tan, is white around her private parts and buttocks leaving her looking like she is wearing a diaper.
