Catullus and translations:

To orally sodomize someone is actially irrumare; pedicare is just the regular anal kind. They both appear in the first line of Catullus XVI.

 

Btw: I found this poem also referred as "Carmen XVI".  I had never considered that the famous "Catulli Carmina" could also function as indicators of HH's nickname to Lolita ( I always thought "my Carmen", "Carmencita" aso was limited to Prosper Merrimée's "Carmen")
