Is "Lumpy Jumpers" a term which is acceptable?

Ladies,

Remarkably this term was used ( in my work) by a woman on the basis that male “banter” is OK. I can only assume that she meant no harm and hasn’t experienced BC. Thoughts? Council? Before I wade in.

Hi 

I am slightly confused is lumpy jumpers a male banter term for women in general? I understand that women can be sensitive to derogatory comments from men in the work plaCe but I don’t get the link to BC? 

If it was me I’d ignore it as I’m struggling to come to terms with what I’ve been through anyway and wouldn’t want to make myself an unwitting target. 
The men that banter like that are not going to change because you’re upset in fact they’ll probably do it more.
