igg (ĭg) Slang
Share:
tr.v. igged, igg·ing, iggs
To ignore or snub (someone).
n.
A snub or rebuff.
Our Living Language Igg, a shortened form of ignore, seems to have come into American speech from jive, the special jargon of black jazz musicians in the 1930s. Its use has since spread beyond musicians into African American communities throughout the United States. The reduction of a word to its initial syllable is a common source of slang or informal words (such as diss, meaning “to show disrespect”), especially among groups of speakers who like to remain avant-garde in their speech. Often such words come into general use, as in mic for microphone.
