is where its at
Right now I can just think of "puta, mierda, me cago en todo (fuck everything, lit. I poop on everything)", so no, no religious insults. Since I like to think I use "cool" insults I usually say "Me cago en Satán" (Fuck Satan), and some people do find it offensive (e.g. my mum ).
Lit. "I poop on Satan"?
