also: がきども
noun
damn kids; brats
Derogatory term for children, often used in frustration or contempt. The plural suffix 共 adds a dismissive tone.
近所のガキ共がうるさくてかなわない。
The damn kids in the neighborhood are so noisy I can't stand it.
あのガキ共、またいたずらしてるぞ。
Those brats are up to mischief again.
From 餓鬼 (がき, 'hungry ghost; brat') + pluralizing suffix 共 (ども). The term 餓鬼 originally referred to a preta in Buddhism, later used as a derogatory term for children.
