A Rubedog
When you get so drunk you forget your sister is your sister and you just go for it like it’s a normal thing.
I drank so much I thought my sister was my friend. That’s a Rubedog.
I had sex with my sister and didn’t even know who she was. That’s a Rubedog.
I got so wasted I tried to kiss my sister like she was my crush. That’s a Rubedog.
