Grumball
The collective noun for a group of (usually middle aged, to more elderly)men complaining about boringly repetitive topics. These grumpy gatherings will traditionally congregate around the bar rooms of sporting clubs or a secluded corner of a social function. The introduction of fresh ideas, or participation in the discussion by a passing spouse will be instantly shunned by the collectively insular nature of the group.
