Sneaky dicky 

In middle of the sex when the penis enters the butt hole instead of the vagina.

Nooki : Hey Ola, why are you walking funny ?
Ola : aah, last night, my new dude, did a sneaky dicky on me.
Nooki : Ouch !

sneak dick monkey 

In nature when the alpha male is mating with the females of his choice, the sneek dick monkeys come up from behind to mate the females when the alpha is not looking.

My supposed homeboy pulled a sneak dick monkey on me and tried to get at my girl when I was out of town....

sneak dick

someone who without your knowledge or consent, forces a penis upon you with intent to rape and or injure. This is done very stealthily, the equivalent of the ninja buttfuck.

Watch out for Jason Pettengill, last night he sneak dicked his brother, hit him hard with the ninja buttfuck
