Up and Down The Slide

Wanna Fuck?, Let's have sex.

Another term for fucking. If you want a guy to know that you want to fuck him, say this phrase and he'll understand you. Either that or lick your lips...

Oh, and if your guy doesn't understand this little phrase, he's on crack and he's lost his marbles!!! But...try to explain it to him.

Girl: "Hey baby."

Guy: "Hey, what do you want to do today?"

Girl: "I wanna go up and down the slide. Can we?"

Guy: "Sure, let's go!"
