A bimbo means two things as far as I am concerned...
1. A stupid, egotistic blonde, usually with big breasts who wears shit loads of make up. she also has lots of friends that look exactly like her. soooo unoriginal.
2. A bread brand that i discovered on holiday in spain...can also be found in south america, I believe...
1. Girl 1: Hey look at that bimbo and all her cronies. Oh look its Britney!
Girl 2: Thats not Britney, thats Karen.
Girl 1: oh yeah. they all look the same so its hard to tell.
2. (in spanish) hey ma! im going out to get some bimbo!
