 Like in the previous series Dragonball, Dragon Ball Z has many  naming conventions/jokes. Saiyans are all named after vegetables.  Vegeta, both the prince, his king father and the Saiyan home planet  (originally named Planet Plant), means Vegetable; Raditz is  radish, and Kakkorotto is carrot. The villain Freeza (originally  Friezer) comes obvious, and his brother Cooler and their father King  Cold. All Namekians born from the villain in Dragonball were named  after instruments (Piccolo, Drum, etc.) The Briefs family were all  named after underwear, Bulma meaning panties, Doctor Briefs himself,  Trunks, and Bra. And of course, various characters named after  foods. Oolong, as in the tea; Videl, like the onion variety; Ginger,  obvious; Spice; Blueberry; Raspberry; Raisin; Almond; Apple; and in  Dragonball there was an entire family (of about 12) named after  desserts.
