if a piece of trash had the nerve to try to 
hit a teacher during the entrance ceremony,
إن كانت هنالك قمامة تجرّأت على
،محاولة ضرب أستاذها أثناء مراسم الدخول
si cierta basura intentara
golpear a un profesor al ingresar,
si cierta basura intentara
golpear a un profesor al entrar,
si jamais un idiot ose
lever la main sur un professeur,
se ci dovesse essere un rifiuto che osasse colpire 
un insegnante alla cerimonia d'ingresso
se tiver algum lixo que teve a coragem de bater
em um professor durante a cerimônia de abertura,
если вдруг какой-то мусор
решит ударить учителя на линейке…
