These lollypops always seemed to be chubby to me, so chubby chubs always stuck in my head as their name rather that the actual Spanish name that came from the word chupar, meaning "to lick or to suck".
These round lollypops have been around since 1956 but didn't get to our part of the world until the late 70's and now found in over 150 countries. Their logo was designed by the famous artist Salvador Dali.
