The noise a chicken makes. Not usually said around chicken, more of a call or holler to get your buddies attention. Also pronounced "Yigek". Started by Matt Maher, Matt Sprecher and Eric Edelmann in Walnut Creek, CA in 1998. Many a shirt was made know as the "bagek shirt" which featured a drawing of the bagek chicken on the front holding an unsidedown "sur" sign. Shirts sold quite well for about $15
