Mud-Vein Technique 

A martial art technique pioneered by The Justin, which involves shoving your fist so far up someone's ass, that you are able to use two fingers to poke their eyes out from the inside. An ultra-violent method of creating good fun.

You best check yoself before I bust out the mud vein technique on yo ass.

Mud vein 

Anal cavity used for sexual activity.

Bitch's sloppy box was so big, I had to toss it up her mud vein for some friction.

Mudvent 

A type of fart that feels as though a turd is blocking the anus, allowing the smelly gas to pass through or around the turd, not not allowing for the typical fart sound that comes from free flapping anus tissue.

I need to clean out this mudvent. My farts feel like I’m shitting myself.

muddvein 

Dull and repetitive. Total bullshit. Something that makes you feel like you're exhausted because you feel like there's mud running through your veins. You feel trapped, or caught. The situation is annoying or is growing in frustration. Something that feels totally moot or pointless.

I hate how muddvein this job is.
When I hear Janey talking, it always makes me feel so muddvein.
I feel so muddvein when I'm here.
Have you ever felt so muddvein while talking to Lyle?
