Go ahead, Mr. Joestar

A phrase spoken by D'Arby (Older) in the best anime called jojo no kimyou na bouken. This is a very popular phrase and fans will say it without hesitation instead of just "Go ahead." It also shows extreme confidence and strength while talking. It should be normal to take on D'Arby's accent while speaking.

Person 2: Go ahead, Mr. Joestar!
