Lola is almost like
Bertha in that it is a name which developed a particular image a while ago and the stereotype keeps getting reinforced by new media events.
Lola first got its overly sexy image from the actress and dancer
Lola Montez:

Montez herself has been portrayed in many books and films.
The name's image was reinforced by the character
Lola in the Broadway musical "Damn Yankees" in 1955, where she sings the song "Whatever
Lola Wants,
Lola Gets":

Then there was the 1970 Kinks song several have mentioned:

Then in 1978 you had the
Barry Manilow song "Copacabana" about "
Lola the showgirl":

It's fascinating to me that this name still has this image in 2012 even for a lot of young people. It's one of the longest running stereotypes other than the idea that
Bertha has to be fat. This also shows that there is a lot more to the "meaning" of a name than just its etymology. :)
