fer right is the combining of i know right and fer real. its used loosely and fits almost in any moment
hey, why did i did i go out last night and spend 300 dollars at the bar...dumb huh..."friend" ..fer right?!
combining the words... "I know right" and "Fer real" into one word making it easier and more clever.
Person 1. " oh god did u see "blank" last night at the bar, he was being such a skeeze?
Person 2. Oh i know, fer right?!!?
