BMS did seem to pick on Ogura...don't know why.
The last part of that sentence means, 'like a woman' or 'similar to a woman'.
In one episode, Rion called Ogura an 'onabe' (オナベ), which is a woman who looks like a man (the opposite of a 'shemale').
The same episode Rion called Acky a locust (バッタ).
I think, this is more of that stuff.
It's really difficult to translate because I can't figure out if the first word has 3 or 4 katakana.
At on point in the conversation, Airi says: "She can't help it." (about Ogura).
I think, Rika is saying something about Ogura's body shape. But it's just too censored, to work out
