Where does "to make out" come from?

Is there any logical explanation for how the phrase making out came together?

I know that it has sexual implications (at least kissing, with the intent go further), I just can't imagine its ancestry.


Solution 1:

Make out has been used with a sexual meaning since 1939.

The third edition of the NOAD reports the meaning of make out is, informally, "engage in sexual activity", "make progress", and "fare".
