A small ball, often referring to a pellet or BB pellet used in air guns.
Compound of 'bee' (the letter B) and 'ball,' since BB pellets are literally small round balls about the size of a 'B.' First used in the 19th century as air gun ammunition became popular.
This word perfectly captures how English speakers nickname things by their appearance or sound—'bee ball' sounds like 'B ball,' which looks exactly like what it is. Kids have been calling them BB balls for generations without realizing they're punning on letters!
