Eatin' britches is when you're so full from the food, you're like, 'I'm not even mad at you, I'm just eatin' my own britches.'

After that whole feast, I'm not even mad at my aunt. I'm just eatin' my own britches.

I ate so much, I'm eatin' my own britches and I might be sick.

This is the best food I've ever had. I'm eatin' my own britches and I'm happy about it.
