The description for the Quroum badge on Stack Overflow says:
One post with score of 2 on meta.
Sounds to me as if I need exactly one post with precisely a score of 2.
Wouldn't this be a better description?:
First post with a score of 2 or more on meta.
Most badge-descriptions of also use the words "First" and "with a score of ... or more" .
Okay, the usage of the word "First" also causes some ambiguity. As SingerOfTheFall suggested:
At least one post with a score of 2 or more on meta.
