supergroupoid (Definition)
Definition 0.1   A supergroupoid $(\mathcal{G},\gamma)$ is a groupoid $\mathcal{G}$ equipped with an involutive automorphism $\gamma : Id \mathcal{G} \to Id \mathcal{G}$ , that is, $$\gamma \circ \gamma = Id \circ Id \mathcal{G}.$$

Remark: A supergroupoid is a particular example of a $``N=1''$ supercategory with all invertible morphisms and an involutive automorphism $\gamma$ .
