a bruntski is when you are with a female who has a larger set of breasts than usual and they are bare you put your face imbetween them and make your lips vibrate while making the bbbb-ish noise...then you squeeze the breasts together and contunue the bbbb-ish noise and then while doing the bbb noise you yell bbbbbbruntski as you pull your face out of her chest
