This green glass with a gold metallic base was made by Imperial Glass Company for Trader Vic's. Morgantown Glass Company was occasionally contracted by Imperial Glass to produce these if their production line was at capacity. The glass has "BIG SHOT" and "XXX" embossed on the bottom and looks like a bullet casing.
