Caveat emptor, Azeri for "more crack." It crept it's way into the Azeri culture in the big crack panic of Summer '88.
"Caveat emptor!" the little children would say to the man who drove the crack truck/lorry around local neighbo(u)rhoods. "No more!" he would say to the children!
'Caveat Emptor' is also the name Whoopi Goldberg went by in the early 70s.
