How familiar are you with Dora the Explorer? Probably pretty familiar, but just in case you've managed to not get intimately acquainted with the show (lucky duck!), let me recap part for you.
In pretty much every episode, Dora and her monkey friend, Boots, encounter Swiper the fox. He tries to take whatever it is that they have been collecting in their travels. Sometimes he succeeds, sometimes he doesn't.
When he is going to make an appearance it is accompanied by very distinctive Pink Panther-esque music. We can see that he's coming before Dora and Boots can, but when they finally spot him they chant, "Swiper, no swiping! Swiper, no swiping! Swiper, NO swiping!". If he takes the thing anyway he says "heh heh heh (and tosses it like up in a tree or something), you'll NEVER find your _________ now!". If they are successful in turning him away, he says "Ohhhhhh, man!", and then leaves.
Somehow at our house, this whole series of phrases has become synonymous with a definite no. Like as in, no, I'm not just saying don't ________ even though I want you to, I really mean it.
So recently in the grocery cart, I witnessed the following:
Scene: The girls are sitting next to each other on a bench type grocery cart meant for two. They're being wild and crazy per usual and have decided that tickling each other is the way to spend the ride. Elizabeth apparently gets tired of this (probably Lilli has managed to actually tickle her back a few times, which of course is not as fun) and shouts:
E: Lilli, no tickling! Lilli, no tickling! Lilli, NO tickling!
Darling Little Lilli: Ohhhhhh, man!
