Top Definition
Dirty fungus that appears on the ceiling after you have had sex for way too long in the shower. It more often appears as yellow dots. Please clean this up immediately, for it is incredibly disgusting. If left for too long it can be toxic.
Aww gawd, you got your Fuck Fungus all over me!
