Nintendo Sex Tune Sung by Spanish Transvestite Band 'Superputa'

Here's a piece of news I stumbled upon today that I couldn't make anything of, other than the fact that there are some Spanish transvestites out there (Superputa is the name of the band) singing a song entitled Nintendo. Where they come up with the name for the song and why Nintendo in particularly, beats me, but it's fun to watch and listen to the tune resembling 8-bit game tunes. Kotaku posts the translated lyrics and gives the name of the band and song, but other than that, nothing:

"Don´t be so greedy and invite me for a drink (2x)
If you do it baby, I´ll take off my clothes
Don´t be so greedy and invite me for a drink (2x)
If you do it baby, I´ll kiss you in the mouth

C´mon baby, come into my room
C´mon baby, I´ll fellate you
How? With my mouth

Don´t be so greedy and invite me for a drink (2x)
If you do it baby, I´ll take off my clothes
Don´t be so greedy and invite me for a drink (2x)
If you do it baby, I´ll kiss you in the mouth

C´mon baby come into my room
C´mon baby i´ll fellate you
Where? On your di..."(well, penis of course).

Where did the transvestites get their inspiration to make the "catchy" Nintendo song? Why is it called 'Nintendo' and not 'Fellate You' if they're going to relate to sex? OK, I'm not trying to spoil anyone's fun here, but what has the song got to do with Nintendo consoles, games, controllers, or anything related to the Nintendo brand? Leaving the lyrics aside, it's only the tune that resembles 8 bid game tunes (probably made with a certain Nintendo game, but nobody's saying anything), except Nintendo wasn't the only one to make 8 bit games. I don't know, I'm missing something for sure...
