squicking

The practice one takes up when skullfucking becomes tedious. Skullfucking is the easiest of the two acts, as you only have to remove your partners eye to get somewhere to stick your thingy. A proper squicking requires you to trephine your partner (make a hole in your partners skull) and pork its brain this way. Aiming for the gap between the two hemispheres is said to provide you with firestorming orgasms.
