Ah, making out in cars...lol how did you miss this nostalgic little piece of Americana?
Usually, it's...man it's hard not to say "making out" in defining "making out"...petting, necking (such as french kissing), or grinding while in a car. Aphrodite's definition is spot on. I have never heard of sex in the car being referred to as "making out"...usually we (well, they...lol can't include myself on this one

) call sex in the car by the eloquent and fitting phrase "sex in the car."
We are a simple people.
