Oh Them Dudes

Pineapple Express features a prologue set before World War II where the military is testing marijuana on a soldier, played by Bill Hader. While high, he complains that the army is full of "dudes," i.e., males.

This is an anachronism. Anyone using "dude" in the 1930s, and for some time after, would have been referring to either someone very well dressed or a clueless Easterner out West (or both).

All I can says is...Dude!
