Two natives sit in the bar getting shit-faced.
Almost closing time, "Brother, you gonna snag?"
"Yeah, I'm taking her home."
He walks over, she gathers her things. Walking out together, he takes her to his car outback. They stay messing around then start having sex. He starts to get carried away. He looks down at her. She looks up at him and says, "Slow down, cousin, you're going too fast..."
Listen up, buttercup. This joke is funny because the dude is about to get it on with some lady he picked up at a bar, but then she stops him by calling him "cousin," implying they might be related. It's like, surprise, incest is wincest...except it's not, because it's gross and probably illegal. You know that the term "Native American" includes a wide variety of distinct tribes, bands, and other organized cultural groups, right? You seem like the type who forgets that.
