גיבור, כל הפְּרֵידוֹת קשות
אבל מצאנו בשבילך דרך לְהִתגַבֵּר...

Dude, all break-ups are tough
But we found a way for you to cope...

The word gibor גיבור means a hero. Thanks to this commercial as well, people started to use it as 'dude', 'bro', something like אחי.

גיבור and להתגבר are both from the root ג.ב.ר. Do you know any other words from the same root?
