badumpkin

Its like a blumpkin except with a bday turned on at various intensities. There are 5 levels of badumpkins:
Lvl 1- Breezy mist
Lvl 2- Drizzly
Lvl 3- Noticable Rainy
Lvl 4- That thing is on high
Lvl 5- The water is pushing you up in the air.***

***WARNING- Do not try a level 5 without stabilizing walls to keep you from flying off into a wall.

Hey I got a level 4 badumpkin last night from Ferrari.

Badumpa-Trump

An enormous old white man booty, likened to that of Donald Trump’s giant ass.

We have to purchase extra large adult diapers to fit grandpa’s badumpa-Trump.
