Double reverse blumpkin

When a person is upper decking a toilet and another person is shitting backwards on said toilet giving oral sex to the person doing the upper decking.

The only reason I like house parties is pulling the old double reverse blumpkin before I leave.

Blumpkrimjob

The act of performing fellatio whilst the receiving party defecates. However, during the act your tongue intermittently embarks on a pilgrimage to brown town.

Stacey was giving me a blumpkin and decided to brave the depths of the nether portal thus the blumpkrimjob was born.

Rose Blumpkin

Basicallly while you are getting a blumpkin you are reading a magazine and smoking a cigarette.

Tony: Yesterday I was taking a shit, smoking and reading a magazine and got my first Rose Blumpkin

Double Blumperdecker

When one person shits in the water tank, preferably onto the ballcock, while receiving oral sex from a partner who is sitting on the toilet, AC Slater style, also taking a shit.

So I went to leave an Upper Decker in Bill's toilet, but Mary came in and offered to give me a Double Blumperdecker since she had to shit, too.
