Need help finding a song

Hi everyone!

Since I am looking for a bollywood song, I figured why not post my topic here. I am looking for a bollywood film song but I don't know all the words to it. But it goes something like this....

"thori si masti, thori sa nasha....dum maro dum maro yaron....dum maro dum maro yaron....."

and I don't know the rest. Its kind slow but a little fast and is has like a spanish type feel to it.

If anyone knows, please let me know. Thanks a bunch in advance. 😃
