I.N.S.E.C.T.

M.A.N.T.I.S. was a superhero on the SciFi Channel with his own series of the same name. It became a running gag on Caption This! to refer to M.A.N.T.I.S. as any other initialized insect than his actual name. Here's a few examples: M.A.G.G.O.T., T.S.E.T.S.E.F.L.Y., D.U.N.G.B.E.E.T.L.E., B.O.L.L.W.E.E.V.I.L., C.H.I.G.G.E.R., E.A.R.W.I.G., S.T.I.N.K.B.U.G., R.O.L.Y.P.O.L.Y., and S.T.I.C.K.I.N.S.E.C.T.
