I was going to have my character call his (female) friend "housenko" in conversation, as a nickname, meaning "caterpillar." Yes, not as traditional as "sweetheart" or "darling," but he means it endearingly. However, according to slovnik.cz, "housenko" can also mean "grub." (!) In English, calling someone a caterpillar can be cute, but to call someone a grub is just an insult. So... in Czech, what's the connotation of "housenka"? Possibly cute and endearing, or equivalent to calling someone a worm?
