a cat shit in my mouth
When you wake up and your mouth feels like it was used as a toilet by a badger who had a bad day.
He posted on Twitter: 'I think I swallowed a garbage can. Cat shit in my mouth.'
His friend called him: 'You look like you’ve been mouth-fucked by a pig.'
She sent a message: 'I woke up and my tongue tastes like a gym sock.'
