facan't
Facan’t is when someone is a total ass but you can’t say it because you’re too lazy or too scared to actually curse them out.
My mom said I had to clean my room, but she called me a 'facan’t' because she was too tired to say 'fucking cunt.'
My teacher said I was a 'facan’t' because I forgot my homework and he didn’t feel like yelling.
My brother called me a 'facan’t' because I ate his last slice of pizza and he was too full to argue.
