Is an acronym for the words Based On A True Story. Can be used in many different situations, for an example when referring to a film. Might also be used when telling a story or a rumour. If exaggerating, B.O.A.T.S. may be used to guarantee the truth (or some truth) of the story. One should though, observe that there is a thin line between B.O.A.T.S. and T.S. (True Story). B.O.A.T.S. is not always reliable and one should be aware of the fact that there might be a very small amount of truth in a B.O.A.T.S. statement.
Jack - Who came up with the Texas chainsaw massacre story dude? It's really fucking stupid.

John - You shouldn't be too sure about that.

Jack- Why?

John - It's B.O.A.T.S.!
