Shit [Moms name here] Shut up and fish!
Shit was also Mom's fav swear. Except that one time when I was around 15 and she said FUCK. Truth be told I was so shocked I had nothing to say and felt like I'd been struck deaf for a bit. It took DECADES and I finally said, remember when we were in the car, did you say- she knew exactly what I was going to say and fessed up with "yes"
Shit
Asshole
Fat ass
these were common, the others not so much.
