Japanese word for "number one". A daily opening bit byXM-Sirius Radio personality Ron Bennington of the Ron & Fez Show where he encourages the listeners to call in with what they would consider the number 1 news item of the day. After he says "Ichiban" a sound clip of people chanting "ICH-I-BAN..ICHIBAN!!" is heard before the caller is put on the air.
