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.
Outercourse is t3h sex
Pretty much the opposite of intercourse, except with clothes on. It consists of male/female couple rubbing up against each other for sexual pleasure.
Damn I literally just had an orgasm for the outercourse.
I know! It was great.
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.
The act of grinding and cumming to completion without ever entering the body.
"Me and my girl had outercourse, man her jeans felt so good."
