"Leggo my eggo" is a former German expression for "Bite me" used in the late 70ies and throughout the 80ies. "Leggo" comes from "Lecken" what "lick" means. "my" is an easy bavarian "mei" ("mein" - in this case "meinen"). "Eggo" equals "Ego" the first person - so "me". Together it´s like "Lick myself" (German "Leck mich") or roughly "Bite me".
