 Get the peniimug.
Get the peniimug. A word made up by people uneducated in the ways of etymology. NOT THE PLURAL OF PENIS.
The rule with aplural form with an I is derived from latin and is only applicable when the word ends in -US, and has no relevance whatsoever when the word ends in -IS.
When a word ends in -IS, the correct plural form is, in fact, -ISES.

Get the peniimug. A false plural for "penis" made up by the same smug pseudo-intellectual dorks who say "boxen" and "ignorami" and "virii". Also, most of them wear suspenders use UNIX (variants of which they call *NIXen).
Guy 1: "Some ignorami stuck their penii in my Linux boxen and now they're borken! This is worse than Winblows boxen with all their virii!"
