2 Chainz says he ain't throwin' in the towel on Conor McGregor -- saying he wasn't just impressed with the way he fought ... but LOVED the fact he still went clubbin' after the fight.
As we previously reported, Conor hit Surrender nightclub hours after losing to Nate Diaz at UFC 196 -- and then went to a bikini pool party the very next day.
As 2 Chainz pointed out ... it's much different from the way Ronda Rousey handled her big loss.
