The name given to a villainous person that wears a pumpkin on their head on Halloween sitting on a toilet taking a shit with the door unlocked waiting for someone to walk in and give them a blumpkin on the scariest night of the year.
I waited for several hours as Lord Blumpkin last Halloween at Kate's house when she finally walked in and gave me a Blumpkin.

When a man is receiving oral sex from a woman and is defecating at the same time(aka blumpkin). However while defecating the woman takes a hold of the fecal matter and forces it back up the anus, hence the term reverse.
In simple words, a woman is giving a blumpkin and shoves the shit back up the mans ass.

A female is sitting on the toilet as her male lover is exiting the shower that she had occupied only moments ago. She had a turtle head poking its unruly neck out due to the deep dicking she had received in the shower prior to this. As the male passes the female she gobbles down his penis in the heat of passion they were still clearly still in. This is something that is in general unplanned and considered highly taboo. However, the two people had in fact not only been in the act of the reverse blumpkin but, had done so accidentally. Hence the accidental reverse blumpkin. The two never spoke of it again. Both feeling ashamed of committing such a perverted act.
I bet they didn't see that accidental reverse blumpkin coming before they hopped in the shower like a couple of wild dogs in heat. Its ok, Jesus still loves them....
