chubby bunny

Chubby bunny is an informal recreational and hazing game that involves the placement of an increasing number of marshmallows or similar items such as cotton balls into one's own mouth and stating a phrase that is intended to be difficult to say clearly with a filled mouth. The game is often played where marshmallows are readily available, such as around a campfire. Variations include similar-sounding phrases such as pudgy bunny, fluffy bunny, fuzzy bunny, chubby monkey, and chubby buddy.
Although the origins of the game are unknown, a 1959 Peanuts comic strip shows Snoopy's mouth being filled with an increasing number of marshmallows while Charlie Brown keeps count.
The once-popular TV series What's with Andy? might have contributed to its popularity in the 21st century after airing an episode in which protagonist Andy Larkin and his friend Danny do the challenge.
