Splintercourse 

The act of having sex with a man who has a tiny dick.

His dicks so small it would be splintercourse instead of intercourse.

Shintercourse 

Similar to sexual intercourse, but only involves the shins of both parties involved. Any contact with any body part other than the shin renders said shintercourse as void.

Jenny and I had some sweet shintercourse last night, so we didn't lose our virginity or get any STDs!

Robbie and I tried to have shintercourse last night, but our knees touched, so it was technically just sex.

squintercourse 

Squintercourse is two people with bad eyesight doing the wild thing.

Pasquale: So how did your night with Debbi go?

Enrico: We both took off our glasses and it turned into a total squintercourse.

I believe at one point I was boffing her bellybutton.

Pasquale: Yikes!

Shintercourse 

When one uses their own shins to create sexual arousal/ spark orgasm, such as rubbing the genitals with the shin to result in climax.

Dude, rub your shin down my thick crease, I require shintercourse.
