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 1: So it's my turn...
Person 2: Go ahead, Mr. Joestar!
"Go ahead and take out the garbage, then when you come back in, go ahead and clean out the fryolator, then when you're done with that, go ahead and clean up the shit someone smeared on the wall in the bathroom."
