Trash Talkin' Translation

Teaching Nutrition at the nursing college has been not only a great way to share my passion for nutrition, but also to win 34 new admirers. I get at least 5 invitations each time I teach to either: student's birthdays, sports events, church, dinners. I mean I knew I was a big deal, but really... So I decided to take them up on the invitation to play volleyball one evening. I made arrangements to bike out to the college and then spend the night at the convent next door (no, working with the Protestant organization has NOT driven me to extreme Catholicism, I won't be putting on a habit... yet) The nuns are great company, plus they make their own booze out of lemons- yes, my stay reeks of ulterior motives. After greeting the nuns, I head out to the volleyball field, where an intense game of volleyball ensues. Being a good 3-4 inches taller than the rest of the team, (which I used as a hands on, in class example of effects of malnutrition) I was at the net as the spiker. The saucy student on the other side began a fair amount of trash talking at the net, so late in the game, the score was close, the intensity high, and I spiked it into the Ugandan girl's face, then proceeded to yell "Nogaamba ki, hati??" or "What's up, now?" Which silenced the other team. I don't think that translates.....
