look up any word, like the eiffel tower:

First heard on Rizzoli & Isles. Jane Rizzoli claims it means "Life Long Best Friends Forever" while she is canoodling her best friend (and obvious lesbian lover) Maura Isles in front of a nice ass red car. We all know it means "Lesbian Lovers Best Friends Forever". But Jane can say what she wants. It's all cool.
Jane and Maura are clearly LLBFFs, as seen in basically every episode, where they engage in hardcore eye sex and display public affection more than needed.

An acronym which stands for the "life-long best friends forever" relationship between the two leading female stars of Rizzoli & Isles.
It's such blatant innuendo that it redefines the term 'subtext'.
Jane and Maura aren't together! They're just LLBFFs!
