Flavor Rape

Is when you're about to eat something and you think you know the flavor, but instead you are surprised with a completely unsuspected taste.

Cousin 1: So how does my mom's spaghetti taste?
Cousin 2: I thought I wouldn't like any spaghetti my mom didn't make, but I just got Flavor Raped in my mouth!
Cousin 1: Yeah, hahahahaha, I remember my first Flavor Rape. :D
