ssssssssssssss. Nasty birdie. An Izzie guess - we thinks vobis has something to do with 'you' or 'yours'. Volis - wish or want - maybe mecum is meeee and dicere is definitely 'to talk or speak'. Quaeso could be cheese but seems most unlikely.
So, in future you intend to abide by Izzie's wish to always talk in Latin?
Izzie's knowledge of Latin is limited to what we can guess from English words - which of course does not include declensions of any variety so except in the most limited and obvious cases (The ugly 'us' ending) the Iz can barely distinguish between nouns and verbs. Though we do remember that the verb endings for the various persons seems suspiciously similar to the Russian ones.
*Just tried tossing the whole thing into the Oracle of Google but they won't let this serpent get away with such laziness. And a dictionary is no good when you don't know how to convert words to their generic form without the specific case or verb endings
