tijuana rainbow 

When you eat some tasty tacos from the roach coach, and then you have to shit something fierce.
You fall down on all fours and blast 100psi diarrhea out you ass while puking all over the shower. making you look like a pretty rainbow!!

I wouldn't eat there, last time i did i ended up doing the tijuana rainbow!
