 == Nepicxo and Eks- == 

 :One specific objection to the -iĉo proposal is that *nepiĉo ""grandson"" is homonymous with ne piĉo ""not musical pitch"", which in Esperanto slang can mean ""not a cunt"" 

 I dont understand the relevance of the bolded section. This article is talking about an objection to -iĉo. The objection exists because 'nepiĉo' resembles vulgar language, not for sounding the same as 'musical pitch'. I think the bolded section should be which in Esperanto slang means. 

 Now about Eks-. 
 :Eks- is also jokingly used in this sense: eksvirkato ""castrated cat"" (lit. ""ex-man-cat"") vs. *katuko''. (Wennergren, Bertilo. ""PMEG - UK"". 12-12-08 .)   

 I don't understand why it says ""jokingly used"". According to the PMEG this is an actual function of the root 'eks-', and it shows no indication of the usage being anything but accepted and serious.   "
