Basically having intercourse, without really going in. Hence, outercourse, also known as dry sex or dry humping. Some people prefer this since there is no direct skin-to-skin contact, meaning... No STD's or pregnancy (usually). Can lead to the point of orgasm for both male and female.
Non-penetrative genital contact. Sexual contact that is not intercourse, oral-sex, or anal-sex or sexual contact where neither partner has a penis. Partners rub their penis, vulva, anus, clitoris, etc against each other. There is still a risk of STD/STI because there is still genital contact. There is also still a risk of pregnancy if ejaculation occurs.
My girlfriend and I have outercourse so that she can come too. I rub my penis against her clit before I penetrate her.
Dry humping or grinding. Sex is intercourse, as in the penis is put "in" the vagina. Fooling around without penetration and staying "out" of the hole is therefore outercourse.
I'm dating this christian chick who's saving herself for marriage. It's not all bad though. We get to have outercourse.
