Leekspin

These are called internet phenomena.

Anyway, this particular one is called "Leekspin". It comes from episode 2 of the japanese anime series BLEACH. In the original show, the scene is a running gag in which Orihime Inoue (the featured character) describes how she plans to make a dinner that everyone else thinks would be barely edible. The four frames were put in a loop to the finnish folk song Lleva's Polka by Lolituma, thus the other name, "lolituma girl" The 6 lines are essentially scat singing, and have no actual meaning. The flash animation has been commented on for it's hypnotizing quality. The video became quite popular and has been remixed and released multiple times with CG animated characters, as one would a music video. See "Holly Dolly"

Anyway, the original clip here:
