  A fourientation of a graph $G$ is a choice for each edge of the graph whether
to orient that edge in either direction, leave it unoriented, or biorient it.
We may naturally view fourientations as a mixture of subgraphs and graph
orientations where unoriented and bioriented edges play the role of absent and
present subgraph edges, respectively. Building on work of Backman and Hopkins
(2015), we show that given a linear order and a reference orientation of the
edge set, one can define activities for fourientations of $G$ which allow for a
new 12 variable expansion of the Tutte polynomial $T_G$. Our formula
specializes to both the Las Vergnas (1984) orientation activites expansion of
the Tutte polynomial and the generalized activities expansion of Gordon and
Traldi (1990).
