Sneaky Nancy 

There are three steps to a sneaky nancy.

1. Before sex, the girl asks the guy if she has protection, and the guy says "yes, right here" and shows her a condom in its wrapper. But he DOESN'T put it on before having sex.

2. When the guy is about to cum, he punches the girl in the head (knocking her out) pulls out, and then jizzes in her hair, and gives her a crazy hair-do with it.

3. Finally, before leaving, he puts the un-opened condom in the girls mouth for her to find when she wakes up.

Joe: Dude, what happened with you and Bridgette last night?
Fred: Hahaha i totally gave her a Sneaky Nancy!
Joe: Seriously? Bad idea...you know she has the clap, right?
Fred: ...OH SH%#

Sneaky 

Being able to get out of a pointless pep rally or band rehearsal without some fat ass teacher finding you and giving you 300 detentions.

Joe: Did you see Steve jump out the window while our teacher was taking us to the pep rally?

Mike: Holy shit I didn't, he's really sneaky.

Sneaky Castro 

To perform oral sex on a woman with a Castro like beard to tikle her inner tighs and her ass(you must grow one or buy one, borrowing is not a good idea.). When the woman is reaching climax then insert a cuban cigar between the beard and into her ass("sneaky"). If you don't have a cigar handy use you finger(extra sneaky).

The last time I gave her a Sneaky Castro, I had to be hosed down.

Sneaky Asian 

v.
1. The act which occurs when a person driving or in the passenger seat of a car looks forward obliviously to the person in the seat behind him or her. Preferably when the car is in motion, the person in the back seat, "Asian", slides an item, i.e. a foot, penis, shoe, sandal, etc., into the slit between the backrest and the bottom cushion of the driver's seat so that it reaches the unsuspecting victim's ass.

(in the backseat of a car)
Guy: Hey Carl, when we get on the highway, give Max the sneaky asian. He won't see it coming.

Carl: Haha, alright. Let's just hope he doesn't crash.

Max: What are you guys talking about back there??

sneak attack 

1. The art of sneaking your unit into a chick's ass when you're doing her doggy style. (Note: This generally is not met with a good response)

Well, I pulled out and then sneak attacked her. She didn't even know what hit her.
