  In his lost notebook, Ramanujan listed 5 identities related to the false
theta function $$f(q)=\sum_{n=0}^\infty (-1)^nq^{n(n+1)/2}.$$ A new
combinatorial interpretation and proof of one of these identities is given. The
methods of the proof allow for new multivariate generalizations of this
identity. Additionally, the same technique can be used to obtained a
combinatorial interpretation of another one of the identities.
