When you're fucking some skank from behind, and right before you blow your load, you pull out and scatter it all over her back.

This is where the name for the x-ray machine at airports comes from being that people photographed with these machines appear to have jumped back first on to a cum grenade.
I backscattered your Mom last night. ;)

Ok, Good for you dad?!? :/
