South american insult. Concha means vagina in Argentina and in the rest of south america is pretty much a shell. However, concha-tu-madre is an insult.

It could have derived from 2 things:

La concha de tu madre! = Your mothers cunt!

or:

Concha es tu madre! = Your mother is a cunt!

Either way is a pretty good insult!
el concha su madre me robó!
