Blumperwax 

This is the act of pouring hot wax down you're japseye and receiving a scolding hot skewer up you're rectum.

Can't believe Dave had a blumperwax last night.

Blumpersal 

Getting a blowjob while the GIRL is taking a shit. Reverse blumpkin.

I thought she was going to pee, but instead she pulled me in and gave me a blumpersal. Nothing like getting your knob polished to the sound of violent diarrhea.
