eating jizz - When you bite into something and it's not what you expected.

When you bite into something and it's not what you expected. Like thinking it's pizza, but it's just a bunch of cheese and your uncle's beard.

I thought I was eating a burger, but it was just my sister's old pajama pants.

I took a bite of the sandwich, and it was just my dad's old gym sock.

I opened the container, and it was just my mom's old lipstick.
