Blumpkeroo 

A blumpkeroo is when you are giving a blumpkin (giving head while he's taking a shit on 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

Last night, I was taking a shit before my shower and my girl walked in for a blumpkin and we ended up doing a blumpkeroo
