first of all i would like to point out that all these definitions are completely wrong. a sneaky panda is a mythical creature rumored to leap from bushes and ejaculate onto unsuspecting passerby's faces.
the common misconception is that a "sneaky panda" is a sexual act between two partners. when the male is pounding the female from behind, pulls out and spits on her back to make her think he just came. but then flips her over and pops in her face. this act however, is actually properly called the"philly fake-out"

"my relationship with my girlfriend hasn't been the same since she was sneaky panda-ed."

Sneaky Panda 

Member of Xbox Live, and supposedly, is a part of an ancient ninja/assassin society. This can not be completely verified, as records of the society are scarce at best. Sneaky Panda is most likely only one name that he uses in his travels.
