For Def Sure
When simply saying 'yes' just isn't good enough. It's like saying yes, but X10. Usually used with an exclamation point
Kat: I'm so hungry
Reuben: Do you wanna get some Chinese food?
Kat: For def sure!
Reuben: Do you wanna get some Chinese food?
Kat: For def sure!
Def For Sure
When someone asks you to do a favor, and you don't plan on doing it, you say def for sure and gradually walk away like nothing happened

Ray and Ed: Yeah def for sure man, I'll def hit you up with that!
Ray and Ed: Yeah def for sure man, I'll def hit you up with that!
