Guy 1: Did you see that hottie walk by?
Guy 2: Yea man, I was sneak peeking that ass.
The act of checking out a girl without her noticing.
Bro there was this super hot chick I saw earlier, I was sneak peeking her.

I sneaked out of the house to get the mail.
When waiting to turn left at a red light, once the light turns green but without an arrow, slam the accelerator down, make your turn and beat the car who should have proceeded straight. Effectively ignoring the right of way.
When a male or female is a creep and keeps sneaking up on you.
Typically the sneaking is done on social networks. Friend requests, pokes, followed...etc. Sneaky texts are also included in this.
The person who is creep sneaking is known as a "creep sneak"
Ex's are usually in this category.
"Man, my ex keep creep sneaking me, he added me on foursquare and poked me on facebook, then sent me a text message! Ugh creep sneak!"
