Conor McGregor -- Irish Consulate Trolls Jose Aldo

The Irish Consulate in San Francisco is charged with promoting Irish interests in the Western United States ... and Saturday night, those interests were trolling Jose Aldo and preventing hangovers.

In fact, just minutes after Conor McGregor knocked out Aldo at UFC 194 -- the I.C. in S.F. went to Twitter with a special message for all of the hard partying Irish fans who made it out for the fight.

BTW, earlier in the week, the Consulate sent out info about a 12 bar pub crawl in Vegas for all the visitors (for charity).
