I wanna have a slice of this!

I am 36 but I don't look old, hardly any grey hairs, I'm not bald and I don't wear old people's clothes but these days almost anyone - except people I know - calls me 'Sir'. I guess I've become an OG too.

P.S. I just looked up its meaning and it stands for Original Gangster or Old Git. I know I'm not a gangster and I'm not sure about the word git either. I guess 'Sir' will do for now.
