Koohii stories:

1) [astridtops] 11-8-2006(266): The hidden Greeks inside the Trojan Horse are getting boisterous as one of them is bitten in the crotch by a nasty insect. If they don't shut up, the Trojans will hear them…

2) [Immacolata] 9-5-2006(76): Or more precisely: the team of horses are getting boisterous because one of them got bitten in the crotch by a horse fly. The kanji also means to roar, make up noise, to kick up a fuss and to make merry. Perhaps it is exactly the etymology behind this kanji.

3) [blaked569] 7-4-2009(27): My horse was boisterous because of nasty bugs in his crotch.

4) [blackstockc] 28-1-2008(10): When a man is hung like a horse his love life often becomes so boisterous that he gets crabs (crotch insects).

5) [Apple_Head] 10-7-2010(5): You'd be boisterous too if you had a horse-sized bug up your crotch!
