Did you know?
You certainly didn't want to be known as a "lollygagger" at the beginning of this century. Back then, "lollygag" was slang for "fooling around" (sexually, that is). That sense of "lollygag" was in use as long ago as 1868, and it probably originated as an alteration of the older (and more dawdlingly innocent) "lallygag." Nowadays, "lollygag" doesn't usually carry such naughty connotations, but back in 1946, one Navy captain considered lollygagging enough of a problem to issue this stern warning: "Lovemaking and lollygagging are hereby strictly forbidden . . . The holding of hands, osculation and constant embracing of WAVES, corpsmen or civilians and sailors or any combination of male and female personnel is a violation of naval discipline. . . ."
