Have you ever been in a situation where a “pack” of dogs, a “gaggle” of geese, an “ambush” of tigers, a “mutation” of thrushes, a “mess” of iguanas, a “fry” of eels (mmm tasety), or something is chasing you, but you don’t know what to call them? (What do you mean, “you could have stopped earlier”?) I mean, if you need to call 911 (or 119 in Japan) for some reason, shouldn’t you be able to give the collective name of that ravenous “troop” of baboons, “clowder” of cats, or the “leash” (3) of snipes (yes, they ARE real)? I know I wouldn’t help if you couldn’t speak proper English (Just kidding I swear … ::whistle::)!
Ok, Ok, so it seems you need to study a little. You should really go here then!
