Origin of phrase is unknown, but legend has it that "Sexy Lance" mispelled the word "Ddoong Boo," online, a word created by EPM. Then while Sexy Lance was high, he randomly blurted "DDING BOO". It is often mispronounced by sindho , Lance's sexy brother who calls it "Dding Goo."
Presently, Sexy Lance's nickname has changed to Dding Boo.
Sexy Dding Boo is the biggest pimp!
