The use of a brown paper bag to conceal the contents or label of a bottle. The appearance of a sneaky pete has become synonomous with alcohol, so concealment is rarely achieved by using one.
when you are doing a chick from behind and real quick you take your dick out, quickly slip it in and out of her butthole, and then quickly insert it back into her vagina. If she has the audacity to ask if you stuck your weiner into her butt, just play cool and pretend you have no idea what she's talking about.
to perform the "sneaky Pete" or "stinky Pete" ask her to do it from behind, bury her face in a pillow, then insert the following; a pencil/pen, a dildo, a tv remote, or anything near by without her noticing. oh and just for fun yell surprise right as you do it,.... why not.
