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.

On Facebook, liking something some one shared, sharing it, then when some one else shares it from you, liking it again.
You may or may not have liked the shared thing on your own profile, but the word has more meaning when you do not like the shared thing in your profile. One shares something on their profile when they like it. Therefore, it is redundant to like it via the like button on their profile.
Could be used in the past tense as "cross-liked".

Anne shared a link to a new music video. I liked it and shared it on my profile. Then Peter liked and shared the video from my profile. So I went to his profile and liked it. Then pretty much all my friends started sharing the link and I went on a cross-liking spree and cross liked every time the link was shared.
