"Barbie bondage" can refer to one of three concepts, depending on context.

Used figuratively, "Barbie bondage" is a metaphor for girls and young women adapting, partly due to outside influence, to the stereotypical bubble-brained, glamour-obsessed gender role that Barbie dolls are said to promote.

Used in a more literal sense, "Barbie bondage" refers to actual Barbie dolls being bound. In one sense this can be a humorous connotation to the fact that new Barbie dolls are secured very tightly to the cardboard backing of the boxes they are sold in.

"Barbie Bondage" is also the noun referring to the soft, long, useful twist-ties used to secure the dolls in the packing (it's not commercially available and can only be obtained from boxed toys.)

In another sense, this refers to Barbie dolls being bound and/or dressed in fetish clothing to purposely evoke a connotation with BDSM. This can be done as a form of art, a way of protesting against Mattel's purported ultra-capitalism and stereotypes, or simply as a sexual fantasy.
