I don't piss where I eat
A person who turns down love because they don't want to be stuck with someone who might end up in the same bathroom as them every day. They'd rather be alone and pee by themselves.
She's cute and nice. But I don't want to be stuck with her forever. I don't want to be peeing right next to her.
I saw the guy from the apartment across the hall. He's got a nice body. But I don't want to be peeing next to him every morning.
He's got a nice smile and a nice body. But I don't want to be stuck with him for life. I don’t want to be peeing next to him every day.
