Forecasm 

Predicting one's own orgasm and letting your partner know in advance when you will orgasm

I told Zana that I was predicting a Forecasm and three minutes later I orgasmed.

a cool way to say "what's up?"

"i'm cool, just chillin"

Alabama Weather Forecast 

What Donald Trump predicts for the weather of Alabama. He knows better than the weather man!

The National Weather Service says no hurricane but the Alabama Weather Forecast says hurricane -- so we better prepare for a Hurricane!

Future Forecast 

What the hell? These people must think we are really stupid. Is there such a thing as yesterday forecast? Duuuh..

Next we will have the Future Forecast but first we will hear from....
Means that NEXT is not Next. Another word that does not mean anything.
Future forecasters will not be fired if they lie like a rug by a certain percentage.

Shipping forecast

A veiled reference to a Black Books episode, used as a metaphor for masturbation. In the episode, Fran masturbates to the shipping forecast because the reader's voice 'confuses her'... but in a good way.

"Why is Linnea taking so long to get changed?"

"Oh, don't worry. She's just got the shipping forecast on."

Sexual forecasting

When a person, in a totally non-sexual context, inadvertently makes a sound or says a word/phrase that is obviously (without a doubt) vocalized in the same way that the person would during sex. This provides a startling, disconcerting glimpse into their private life.

"UGGGGHHHH YESS!!!" moaned Fernanda after seeing her final physics grade. "Whoops ... sorry for that sexual forecasting just then."
