when a girl or good is extrememly great in bed. pretty much the best sex you've ever had.
for a girl, its a combination of having aquafina flow and ridicoulusly tight skills.
for a guy, its when your dick is just that good and your stroke is on point.
also can be a shortened form of good dick/ good pussy.
"Man, I got that good!"
"Damn man, I hooked up with Tonya last night. That girl got that good!"
"Mike stay beating it up, that nucca got that good!"
