Yayo is the spanish word "llello". To make it easier for the english people to pronounce it properly they said "yayo". It sounds the same thing is spanish so STOP TRIPPIN!!!!!!

This word became popular after rapper E40 made a song about it. now i cant say he started using it first, but he had a popular song around 97 called "slangin yayo".

it is true that it first appeared in scarface, but i never saw people writing "yayo" before e40.

he is from the san fransisco bay area and sometimes the "east bay" is reffered to san yay. anyway, getting back on point yayo means cocaine.
i hope i dont go back to slangin yayo-slangin what-- yayo-- to get my mayo.

mayo = money
