Spanish for "yes daddy". You usually say it when you are asked a yes or no
question. Or if the teacher tells you too do something. No
matter if the teacher is a guy or a girl.
Spanish teacher says "Timmy, did you bring an std to school again dear?"
YOU:
SI PAPI !!!!
Spanish teacher says: "Get your hand off of my ass!"
YOU: "
SI PAPI !!" and proceeds to grab her pussy instead.
