Nutswingers- is another slang term for ticks or lice that survive off of the animal/human that they are attached to. I guess kinda like crabs...Without a source to feed them they die...

Therefore if u are a "nutswinger" u cannot function in life without ur host (blood donor) therefore causing ur demise...

Now then...Offense is supposed to be take by this but let's be real...That shit is jsut funny...
