Smashing blumpkin

The act of mouth humping a judy whilst taking a dookie.

I was taking a mondo poo and my boo thang was all horny like, "Me so horny, me love long time." So, I had no choice but to give her a smashing blumpkin.

Alaska Blumpkin

A combination of a blumpkin and an alaskan pipeline.

Shitting while getting a blowjob and then putting it into a frozen condom to fuck a girl in the ass.

I gave her an alaska blumpkin.

Inverted Blumpkin

There are two kinds of inverted blumpkins:

1. To masterbate while shitting on a girls face.

2. To take a piss while getting your salad tossed.

Susie wanted to try something new, so she gave me an inverted blumpkin instead of a regular blumpkin.

pumpkin blumpkin

The same as receiving a classic blumpkin (a blowjob while taking a dump) BUT with the slight variation that you ask the nice young lady or man to wear a jack-O'-lantern on there head while they do it.

Dude you know how I got rid of all of my pumpkins after halloween? I had my girlfriend give me a pumpkin blumpkin everyday this week!

Blumpkin Grenade

Similar to the Jizz Grenade. While recieving a blumpkin, you shit in a big balloon rather than using the toilet. Then have 6-9 of your friends masturbate to you and your partner and then when cumming, jizz into the balloon. Once the blumpkin reciever is cumming, he then jizzes into the ballon. They then throw it at a victim yelling BOMBS AWAY!!. This makes a prank that a victim will never forget for many many years.

Alan: Man, Mitch is such a fucking dick.

Nick: Hey tomorrow lets build a blumpkin grenade so we can teach that bastard a lesson!
