sneaker squid 

To surprise another.

Origin: During mating season, an inferior male squid will lay in wait while a more dominant male squid courts a female squid to lay her eggs. The sneaker squid dashes in and fertilizes her eggs before the alpha squid can do the deed.

He came outta nowhere and sneaker squided me!!! I almost jumped out of my skin!

Sneaky Heckler

A movement that involves two people about to kiss, but one person sneakily cops a feel of the second unsuspecting person just as their lips connect. AKA "the surprise second base"

"Wow, did paul just go for a sneaky heckler on andre?"

"So we were drinking and right before we kissed he tried to pull off a sneaky heckler."

sneaky frogger magician 

When your girl doesnt want penile insertion you have her stand up naked and act like your going to eat her out. You get down in a froglike position, pull out your erect penis, and spring up as quickly as possible and insert your penis in the vagina. If you do it correctly the girls feet should completly leave the floor as if she was levitating. You should then say abra kadabra and show her the live webcam and show her face to the audience. To add even more magic you can insert your penis into the peehole instead of the sex hole.

My girlfriend broke up with me after i gave her the sneaky frogger magician.
