I was able to find the basis of this video from reddit. Its a fan made 3d animation (sorry, no direct japanese link this time) of several meme's. The 2 guys are from a popular (?) gay wrestling movie, many 4channers have probably seen it as a flash animation played/synched to one of Kirby's background soundtracks. The steam roller is from jojo's adventure, and the girl (!) driving it is the vocaloid character Kagamine Rin. The scene is a remake of one of the over-the-top drifting scenes from the anime Initial D.
