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.
A blumpkeroo is when you are giving a blumpkin (giving head while he's taking a shiton the toilet) and you go for a handstand 69 position on the toilet, then your arms give out (or he purposefully does it) and your head falls into the dirty toilet water
