It is a way of saying 'Fuck you' that no one will understand. The main reason for using this, is to be able to say it in front of anyone (Teachers, Parents, Ect.) And not get in trouble.
Teacher: You have detention, young man!
Student: Fukkawaquanoonoo.
Teacher: What did you say?!
Student: Ummm... 'Peace be with you'?
Teacher: Oh...okay.
Student: Fukkawaquanoonoo.
Teacher: What did you say?!
Student: Ummm... 'Peace be with you'?
Teacher: Oh...okay.
