When a teacher goes from being cool to not cool. Any kind of jumper or vest or bright colored blazer would be a symptom of crossing over
Mrs. Dante had the coolest shirt on yesterday and now she is wearing a jumper with letters all over it, she must have crossed over

Crossing the streams: When you're urinating and defecating at the same time, and you maneuver your body just right so you can urinate on your feces while it's coming out.
This isn't a sexual act, but I'm sure someone can figure out a way.

"Dude, I just pissed on my shit while it was still coming out. It was awesome!"
"Yeah man, I cross the streams all the time."

A sexual maneuvre whereby the male (or dominating party if you're gay) turns the female (or bunny if you're gay) sideways and pushes them against a wall. The male will then proceed to thrust into the vagina (for homosexuals, the legs of the bunny must be brought up slightly so he can cornhole you). This looks like a cross from behind. Like all wall positions, this requires sturniess and good leg strength. It is advisable to lubricate when doing this to avoid severe bending of the penis.

The business of thieving, or anything else illegal or shady in nature such as the black or grey markets. Fencing, stealing, and smuggling.
I make my money the modern way, I cross-trade stolen merchandise and contraband on auction websites and invest my jink based on insider stock tips...

I was getting ready to bang this chick when she took off her shirt and I noticed she was cross nippled.

Cross Props
The most awesome form of props. Giving someone props with your arms crossed over one another (the other person does the same). This form of props is only for the most advanced dudes. Not everyone can handle the cross props and you should only attempt it under proper supervision.
