Nibbley-pibbley 

From the NES game "Snake Rattle 'n Roll." Little balls that are eaten to make your tail longer. Depending on the level in which they are found, nibbley-pibbleys have various means of locomotion, such as fish tails or helicopter blades. Nibbley-pibbleys can be orange, purple, or yellow; eating one the same color is better than eating one the color of the other snake, but the yellow ones are the best of all.

Pibble nibble

When a Pibble (a pit bull) nibbles you with their front teeth affectionately while they're kissing you. It doesn't hurt.

Me: Bliss, my pibble, was so excited when I came home from work last night that she kissed my face forever and gave me a Pibble nibble.

Friend(doesn't have dogs): She bit you? Didn't that hurt?
Me: Hell no! It wasn't a bite at all, it was a Pibble nibble, she does that when she gets super excited. It doesn't even hurt- it's affectionate.
