I have no idea, but Catullus has a neater name.
Why you made the correct choice (though this translation is a little different than the others that I have seen):
"How should I explain, Gellius, why those rosy lips of yours
should be whiter than the snows of winter,
when you leave your house in the morning
and when the eighth hour rouses you
from a gentle nap when the day is long?
Certainly there is something: do the rumors
indeed whisper truly that you eat out
the full-grown erections from the middle of men?
Certainly it is thus: they cry out that poor little Victor's
balls have been burst and your lips have been
stained with sucked-off cum."
