"Slaphappy" hits a lot of the same spots as "punch-drunk": when you suffer a blow to the head, you become confused and silly for a while. The "dazed and confused" sense of "slaphappy" first appeared in English in 1936, and by the following year it was being used to describe those who behave with such abandon it’s as though they’ve had the common sense knocked out of them. A 1937 article in the New York Herald Tribune called Ernest Hemingway, a writer known to have had an adventurous lifestyle, "the slaphappy litterateur." Often you will see the word spelled with a hyphen ("slap-happy"), but the closed compound is more common.
