Sack of farts

It's a bit difficult to explain. He overheard me on the phone with my mother, for whom I was trying to set up her Tracfone she got. I had to set up an account and it wanted an email address, but hers is useless because she can't get into it, so I used mine. She thought that would cause a problem activating her phone service because I used a different email address. She kept insisting on it. I said, "I activated the SIM card. The SIM card doesn't give a sack of farts about your email address." Yeti1924 found that hilarious and kept saying it all evening. I also at one point tried avoiding using profanity so I said "God bless America" and he repeated it a handful of times.
