That's an interesting wrinkle, putting down a prejudiced remark with one that's just as prejudiced.
Well, no, it is not.
Since all of the three I cited are intrinsic to and overlooked in the "very american" use of the term bitchslap in that context. Do you see ? It is the term "bitchslap" that I was referring to as american - and misogynistic, and homophobic (in this context), and violent.
Also, my three prejudices outweigh the american one.
Personally, I love the term 'bitch slap'.
'Pimp hand' is way up there for me as well.
