Tijuanan Slip 'n Slide  

The act of sticking a funnel into someone's butthole and pouring warm nacho cheese down into it. Once the cheese is inside, tell your partner to exert the cheese out, this can achieved by putting pressure in your butt or simply farting it out. Once the cheese is oozing out, lick up all the nacho cheese.

I went to Mexico last spring break, you wouldn't believe all the Tijuanan Slip 'n Slide attractions they got over there.
