Masterbating while taking a shit
dude my phone fell in the toilet while I was doing the thumpkin
2. Thumpkin
A more powerful blumpkin; a blumpkin with 'a little more umph.' A quickly and fiercely delivered blumpkin, often resulting in massive amounts of shit water and semen splatter with heavy collateral.
1. So my girl sat me down on the john and we proceeded to experiment with a blumpkin. It went downhill from there and I ended up getting more of a thumpkin than anything else. By the end of it, us and the whole god-damned bathroom was covered in shit and cum.

2. Yeaup, so I pressured Lisa into giving me a blumpkin the other day... bad idea. Instead I got a massive thumpkin that blew out the lights and shattered my mirror. The toilet's fucked too.
