they think say no bueno is the same same thing as saying "no good" but it doesnt work like, it sounds stupid, no spanish speaker says "no bueno" instead we say "eso no es bueno" or just " no es bueno" they also say "vamonos" when they tell to go away but vamonos is plural so is like saying " we go" it implies that they are also coming with us when they just want us to leave.
