yawnversation 

1. The process of yawning while speaking, which transforms both the accent and the language itself into something unbelievably hard to understand for a brief moment in time. Caused by the inability to close one's mouth, a mandatory technique in speech.

2. A phenomenon that occurs in every language of human society. Involves continuation of speech during a yawn, which disables the speaker from closing their mouths making what they say difficult to understand, usually lasts only a second or two. Facial contortions and saliva spraying may simultaneously occur.

yawnversation 

A yawn performed when you are talking to someone who tries to conceal their fatigue by yawning with their mouth closed. Akward facial contortions are a dead give-away to a yawnversation.

Non-yawner: "...so i said, fine, i'll work your shift, but she's all like, no forget it..."
Yawnversation-er:(silence accompanied by eye squinting, scowling and the jutting out of the chin)
