Squeaky Clean [2] 
This is a really painful technique. First the receiver is given a normal wedgie. Once the underpants are firmly wedged in the person's butt crack, the giver turns them around and gives them a Melvin. Not only does this hurt at the front, but when the underpants pull back through the butt crack it burns like hell. This process is repeated several times, normally until the receiver starts crying. This has to be done when the victim is wearing pants, otherwise the underpants don't stay in the crack too well between turns. There are variations where the victim is lifted of the ground with each re-wedge/re-Melvin, and one where two people alternate giving a wedgie and giving a Melvin in a kind of see-saw motion.
