A nasty person who resembles french toast... usually has the following attributes: greasy hair-syrup, bad smelling-burnt eggs, baby powder in hair to try to cover up the grease-powdered sugar. May also be a mysterious whore-nobody knows where it came from and is everywhere.
Man: Hey did you see that Kaitlyn smith chick?
Woman: Yeah she's a real french toast.
Man: Hey, your right!
