Sir can be hip tho lolO man, I remember when I got called "sir" in my 20s. I was in my car in traffic for work in Jacksonville, and this kid rolls down the window in his mom's are and says "Excuse me sir, would you mind letting us cut across?"
Young bulls called themselves that sometimes lol
But OG & Unc it’s ova

. I am in my early 30s, definitely not washed.
. Old head, OG, etc. Look at it on the perspective of a youngin that respects your wisdom and guidance. Trust, I dread being in my late 30s in human years, but when a youngin gives you that title...you flaunt that jawn

don't drink don't smoke at a young age.
