Term used to describe a freshman, either in high school or college, who becomes sexually promiscuous in order to try to gain the acceptance of the upperclassmen. In reality, they will just become known as the school skank, and no one will want to associate with them except guys who just want to use them for sex.
Freshman #1: What has been up with Kelly lately? She's been throwing herself at all these seniors.
Freshman #2: It's really pathetic, she's becoming freshman flesh just so she can fit in.

Senior Guy #1: Hey, who's that chick over there in the booty shorts?
Senior Guy #2: That's the new freshman flesh, I've heard she'll have sex with any upperclassman.
