The act of wearing a life jacketupside down like a diaper in order to make your upper body less constricted. This is usually done while drinking copious amounts of Pabst Blue Ribbon or other inexpensive beers in an ocean or lake.
The process of putting two diapers on a baby or child, rather than one. Mothers who use cloth diapers on their children quite often use the option of 'double diapering'.
Gerund form of multi-part verb “to chin diaper,” i.e., to lazily pull your mask under your chin instead of taking it off completely and deploying when needed.
“Man, it is staggering how many people are chin diapering in midtown today. Lazy fucks look like freaking idiots walking around like that. Sheesh."
