Uncontrolable laughter in an inappropriate situation. Coined by comedian Kathy Griffin.
> Julie: Sorry I couldn't make it to Tim's funeral yesterday. How was it?
> Bill: Oh, it was really sad, but the worst part was when I got a case of the church giggles during the burial. I don't know where it came from, but I couldn't stop laughing.
> Julie: You're sick, you know that? He was your best friend!
> Bill: Oh like you've never gotten the church giggles before. Need I remind you of your nephew's briss?
