sneaky whiteboy 

When a girl thinks a guy has a small dick, only to be shocked at how much larger it gets when aroused.

I didn't think he was packing much until he pulled a sneaky whiteboy on me and I had to choke down 8 inches!

Sneaky Fat 

Is where a person looks athletic and in good shape but has hidden fat.

When you see someone in a gym that has really lean arms and legs and looks fit in shorts and a singlet, but when they take their shirt off they have a chubby stomach and back fat. The person is said to be 'sneaky fat'.

Sneaky Gopher 

When you are with a girl and she doesn't know what holes you are going to go into.

I brought that girl from UND back to her dorm and pulled the Sneaky Gopher on her.

Sneaky Hairstylist

To finish ejaculating with your hand after sex with a female, then acting like you clean your hands, only to get into bed and act like your caressing her hair while your actually rubbing semen in it.

Friend: "Dude, what was wrong with that girl's hair in you bed this morning?"

You: "Oh, I gave her a Sneaky Hairstylist last night."

sneaky ball

where you stand in a crowd of people with your testicle out and if your ball gets cold and no one notices it is out, you win and if someone says SNEAKY BALL then you loose. This is a great family game.
