Didn't everyone hate you after you got 
caught three-timing before summer?
ألم يكرهك الجميع عندما اكتشفوا 
أنّك كنت تواعد ثلاثًا قبل الصّيف؟
Hattest du’s dir mit dem Mehrgleisigfahren nicht
schon vor den Sommerferien bei allen verscherzt?
¿No será que antes de las vacaciones
te descubrieron y ahora todas te odian?
¿No será que antes de las vacaciones
te pillaron y ahora todas te odian?
T’as morflé quand trois d’entre elles
t’ont grillé juste avant l’été.
Non ti odiavano tutte dopo aver scoperto
che avevi il piede in tre scarpe prima dell'estate?
Todas não te odiaram depois que foi
pego três vezes antes do verão?
Так тебя все возненавидели,
как узнали, что ты с тремя встречался.
