<P> Making out is a term of American origin, dating back to at least 1949, and is used variously to refer to kissing, petting, and necking, but may also refer to non-penetrative sex acts such as heavy petting . Snogging has roughly the same meaning in British English and some related varieties of English, except in Hiberno - English (spoken in Ireland), where it is more commonly known as shifting . </P> <P> The sexual connotations of the phrase "make out" appear to have developed in the 1930s and 1940s from the phrase's other meanings of "to succeed". Originally, it meant "to seduce" or "to have sexual intercourse with". </P> <P> Studies indicate that at the beginning of the 20th century, premarital sex increased, and with it, petting behavior in the 1920s . The Continental experience at that time is amusingly illustrated by a letter that Sigmund Freud wrote to Sándor Ferenczi in 1931 playfully admonishing him to stop kissing his patients, in which Freud warned lest "a number of independent thinkers in matters of technique will say to themselves: Why stop at a kiss? Certainly one gets further when one adopts' pawing' as well, which, after all, doesn't make a baby . And then bolder ones will come along who will go further, to peeping and showing--and soon we shall have accepted in the technique of analysis the whole repertoire of demi - viergerie and petting parties". </P>
