2pac- "West Coast in the mutha fuqin' House!!"

heard some guys in a lowrider blasting what i think was an intro to a 2pac song that sounded like him shouting a few times:

"West Coast in the mutha fuqin' House! / West Coast in the mutha fuqin' House!"

had a pretty up-beat tempo with an in-your-face beat

need help finding the song since 2pac has a pretty extensive library and has also featured himself as a guest on a lot of west coast rapper albums not to mention all of the stuff taken from him and used on other artist albums posthumously. Help.

it's also hard to google rap lyrics for the spelling (mutha fuqin', mother ****ing, mutha ****in', mother ****in, etc.)- so i need someone who really knows their 2pac!...at least i think it was pac

somebody's gotta know this
