1/4 inch sneak 

When bangin' the bejesus outta your girl you in one swift motion pull out and plung it in her arse. Also know as the ALLIOOP or COMING IN UNDER THE RADAR.

You should have heard her moan after I gave her the old 1/4 inch sneak.

Potatoes, they are the sneakiest vegetable. 

They live underground so you can't ever see them coming, and they have eyes all over so they can see you before you see them. Coined by Sam of Wisconsin.

Sneaky casserole

When a guy is giving it to a girl from behind and he is at the point of ejaculation and tells the girl he is cumming only to spit on her back and cum in her face when she turns around thinking he is finished

I was nailing my girl doggystyle when i decided i would play a lil trick on her by doing the old sneaky casserole move. When she turned around and got the surpise load i dont know if the look on her face was anger or delight

Sneakatoke 

As Described by Professor Toke (Professor Oaks way cooler Brother)

A rare Pokemon seen throughout the Northwestern United States. Sneakatoke sightings are few and far between due to the sneaky nature of the creature. Catching the sneakatoke is a difficult task because of its high defense and speed. One must wait until the Sneakatoke begins to toke and then throw the pokeball. While toking he is defenseless, I recommend everyone throw a pokeball at every sneakatoke sighting as they are a rare pokemon.

Sneakatoke is often seen smoking a one hitter or vaporizer in public or occasionally a joint, spliff or pipe.

Typically in urban or suburban areas, typically the male species is more common but female sneakatokes have been sighted numerous times.
Usually seen or smelled as they produce a very pleasant aroma, that is the sign of the Sneakatoke.
