Insults are part the language and we are all adults here. I would like to keep collection of insults, obscenities, colorful expressions etc.. Please contribute if can. A few of top of my head: mentula, ae f. = for some reason a feminine word. obscene word for male organ. Catullus wrote a few dedicated poems. lumbus, i m. = gentler term than mentula, for genitals. culus, i m. = arse. Ite mihi in culum! ī in culum! cunnus, i m. for some reason a masculine word. obscene word for female organ. Famous latin language advice from Cicero to always say nobiscum instead of cum nobis. Becuase cum nobis sounds like cunno bis.
