Top Definition
The stiffening of a male's back due to unreleased semen build-up. As unreleased semen runs out of room in the testicles, it spreads into the lower back and hardens into cheese. In severe cases it can spread into the neck. Symptoms include: anger, over-aggressiveness, low patience, lower standards, chronic masturbation, purchasing of prostitutes, etc.
Ben had a tough time getting up in the morning due to his cheesyback.

Ben flipped out on his best friend over some dumb shit because he's got cheesyback.

They bought Ben a hooker because the cheese was creeping into his neck which could have developed into neurological issues.
