This is the male equivalent to a baby shower. When the mother of the child has a baby shower, the father of the child has a Diaper Party, at which his buddies (usually the significant others of the women attending the baby shower) bring cases of diapers and beer.
Hey man, is your Diaper Party the same day as the baby shower?

"Did you hear? Sue went to Mike's diaper party last week and enjoyed it so much that she's been wearing diapers ever since.

A party for an expecting father. This is typically for males only and is the equivalent of the female only baby shower. The guests bring adult diapers and put them on the soon-to-be father. The father is not allowed to use the bathroom and instead must soil himself in his adult diaper whenever he needs relief. Once the diaper is soiled the guests place the father on the kitchen table and change his diaper.
Greg went through an 8-pack of Depends during his diaper party! He should have laid off the White Castle for lunch.

Canadian Diaper Party – n. an event where adult persons consent to gather in a space that is either without bathrooms or where the bathrooms are rendered inaccessible. They are then allowed to wear diapers and listen to music whilst liberally drinking alcohol. These persons, wearing a diaper are encouraged to freely relieve their bowels – as they are likely to reach a state of drunkenness that would warrant such behavior, knowing that they are protected from censure as all other party participants are likely to engage in the same bowel-releasing activity.
“Wow Dan, that was some crunch you took whilst on the dance floor at Tony's Canadian Diaper Party, eh?”

Staying home all day with 3 children under the age of 4 and having your friends and family accuse you of doing nothing all day.
My husband and friends always ask me "what do you do all day?" Well, between Paige (3), Dexter (2) and Weinus (6 months) not's a regular Bon Bon Diaper Party over here!
