Titty fucking. The 8 represents the titties, and the bow of the 9 represents the penis.

89 

When a man pulls out of a woman's vagina during intercourse and ejaculates all over himself.

I just pulled out an 89'd on my chest.

She hopped off my dick too soon making me 89 on my face.

I'm too much of a pussy to properly cum on her like a real man. I prefer to 89 on my gut.

To use a Texas Instruments TI-89 to pass a calculus exam, either easily or with difficulty, that would otherwise be impossible to do in the normal fashion.

I 89ed that test the whole way through, it was so easy then.

I am going to 89 my way through calc 4, I can't do double integrals .
