Um, idk how to describe it

Last night, me, my dad, my step mom, and half sister (4y/o)were hanging out in the Family room. And my step mom stood up to check on the cupcakes she was making. She saw my dads balls and said "I can see your balls". I looked at my dad. My dad looked back at me like he just choked someone "YOU SEE THEM TOO HAZEL?" Like, he was happy about it. A few minutes later he yelled "OPA'S SAGGY PENIS" and my half sister copied him. So me and my step mom sat down on the couch, my step mom said "one time I said 'bullshit' about something, and she copied me" referring to my half sister. My dad yelled ''BULLSHIT'' jokingly. And not by suprise, "BULLSHIT!" "BULLSHIT,BULLSHIT,BULLSHIT,BULLSHIT,BULLSHIT!" Me and my dad were laughing so hard we couldn't breathe. Once my dad could breath again, he said "GRANNY'S CRUSTY VAG" Of corse my half sis copied again. My dad made me get my older siblings. We all watched my half sister copy innapropiate stuff for like 20 mins. I'm sorry I just had to share this story
