Smunching is what happens when you have a boner and see something so unattractive and disturbing it immediately makes your boner go limp. This is not a gradual softening of the penis, this is going from 12 to 6 instantly. This terrible sight has smunched your boner.
You have a boner, you see your grandma taking a shit, you instantly don't have a boner...you've been smunched.
