Not sure if this counts because I didn't swallow but...I tasted a cockroach. I was over at my friend's apartment watching a movie, and it somehow, without my notice, fell on my plate while I was really drunk ( I have a feeling my friend put it there). Nastiest thing ever because I was eating not totally cooked pizza bagels that were pretty chewy. After I felt something weird in my mouth, I spit it out and it was twitching T.T
