A yogurt rat is a species of douchebag. The word originated directly from the latin root of "dumbass". You use this nickname as an insult to call someone stupid and genuinely roast their ass. Have fun. Oh, by the way.... if your name is francisco...... feel targeted by others :)
Person 1: "Hey, did you see Franny today?"
Person 2: "Ugh yeah, he's such a yogurt rat *scoff*."
