Etymology

Origin of bummer1

An Americanism first recorded in 1850–55; probably from German Bummler, derivative with -er noun suffix ( see -er 1) of bummeln “to take a stroll, dawdle, loiter” (expressive verb of uncertain origin)

Origin of bummer2

1965–70; apparently bum 1 (adj. sense) + -er 1

Explanation

A bummer is a huge disappointment. It's a bummer when you try out for a big role in a play and don't end up getting it. The word bummer is a very casual way to describe or make note of a frustrating experience. You can say, "It was such a bummer when we missed the train," or respond to bad news by saying, "Bummer!" The current meaning is from 1960s slang, but in the 1880s a bummer was a "loafer" or "idle person," probably from the German slang word bummler, "loafer."
