Piccolo (specifically his father King Piccolo) was intentionally given the name of a small instrument to juxtapose to how much of a threat he was.
Anyway:
-Every pure-blooded Saiyan has a name basted on Vegetables.
-Bulma's whole family is named after underwear
-Gohan means rice
-Yamcha and Oolong are named after types of tea
-Krillin's name is supposed to mean chestnut
-The Giynu Force are named after dairy products
-Frieza is called that because the freezer is (sort of) where you store all your food
